Answer:

Step-by-step explanation:

The 2 factors of x^2 - 9x + 14 are (x - 7) and (x - 2) because -7 + -2 = -9 and -7 x -2 = 14.

The factors of the quadratic expression  x² – 9x +  14 is (x - 7)(x - 2) option (B) (x - 2) is correct.

Any function of the form [tex]\rm f(x) =ax^2+bx+c[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic function.

It is given that:

The quadratic expression is:

= x² – 9x +  14

Using factor method:

= x² – 7x - 2x +  14

= x(x - 7) - 2(x - 7)

= (x - 7)(x - 2)

The factors of the quadratic expression  x² – 9x +  14 is (x - 7)(x - 2)

Thus, the factors of the quadratic expression  x² – 9x +  14 is (x - 7)(x - 2) option (B) (x - 2) is correct.

From the series, it can be deduced that the sum of the first two terms will be 18.

From the information given, it was stated that the transport charge starts with a minimum charge of R8 and thereafter it was increased by R2 for each kilometre.

The series is also given as S. = 8 + 10 + 12 + 14 +... Therefore, the sum of the first two terms will be:

= 8 + 10

= 18

Expressing T2 in terms of S, and S2 will be T2 = S + S2.

Product of two polynomials can be done by distribution of multiplication over addition. The product of  [tex](4x -3)(2x^2 -7x + 1)[/tex] is [tex]8x^3 - 34x^2 + 25x - 3[/tex]

Suppose a, b and c are three numbers. Then we have:

[tex]a(b + c) = a\times b + a\times c[/tex]

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)

The product result of the given expression is obtained as:

[tex](4x -3)(2x^2 -7x + 1) = 4x(2x^2 - 7x + 1) -3(2x^2 - 7x + 1)\\(4x -3)(2x^2 -7x + 1) = 8x^{1 + 2} - 28x^2 + 4x - 6x^2 + 21x - 3\\(4x -3)(2x^2 -7x + 1) = 8x^3 + (-28-6)x^2 + (4 + 21)x - 3\\(4x -3)(2x^2 -7x + 1) = 8x^3 - 34x^2 + 25x - 3[/tex]

Thus,

The product of  [tex](4x -3)(2x^2 -7x + 1)[/tex] is [tex]8x^3 - 34x^2 + 25x - 3[/tex]

Answer:

88

Step-by-step explanation:

x + 49 = 137 (exterior angle of triangle is equal to sum of its opoosite two interior angles)

x = 137-49

so, x = 88

Answer:

x = 6

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are in proportion, that is

[tex]\frac{MO}{PR}[/tex] = [tex]\frac{MN}{PQ}[/tex] ( substitute values )

[tex]\frac{4+x}{5}[/tex] = [tex]\frac{x-2}{2}[/tex] ( cross- multiply )

5(x - 2) = 2(4 + x) ← distribute parenthesis on both sides

5x - 10 = 8 + 2x ( subtract 2x from both sides )

3x - 10 = 8 ( add 10 to both sides )

3x = 18 ( divide both sides by 3 )

x = 6

since our denominator in 6/15 is 15, we could adjust the fraction to make the denominator 100. To do that, we divide 100 by the denominator:

100 ÷ 15 = 6.6666666666667

Once we have that, we can multiple both the numerator and denominator by this multiple:

6 x 6.6666666666667/15 x 6.6666666666667

= 40/100

Now we can see that our fraction is 40/100, which means that 6/15 as a percentage is 40%.

We can also work this out in a simpler way by first converting the fraction 6/15 to a decimal. To do that, we simply divide the numerator by the denominator:

6/15 = 0.4

Once we have the answer to that division, we can multiply the answer by 100 to make it a percentage:

0.4 x 100 = 40%

And there you have it! Two different ways to convert 6/15 to a percentage. Both are pretty straightforward and easy to do, but I personally prefer the convert to decimal method as it takes less steps.

Answer:

40%

Step-by-step explanation:

6/15 = 0.4 = 40%

All these mean the same them, but what we are looking for is a percentage, which is 40%.

[tex]\bold{\huge{\blue{\underline{Solution}}}}[/tex]

Let's start ,

From the figure, we can assume the beam forms as AD, BC, EF , GH and so on.

Therefore,

[tex]\sf{ ABCD , AEFD, AGHD.. so \:on similar\: to \:each \:other }[/tex]

So,

[tex]\sf{ Angle\:BAD = Angle\:EBC = Angle\:GEF}[/tex]

Or,

[tex]\sf{ Angle\: ADC = Angle\:BCF = Angle\: EFH }[/tex]

Now, By using similarity theorem we can determine their sizes, braces and angles that is,

[tex]\sf{\red{ AD/BC = AB/AE = CD/CF = BC/EF}}[/tex]

[tex]\bold{\huge{\blue{\underline{Answers :- }}}}[/tex]

Answer 1 :-

For answering the above questions we use knowledge and practices regarding the questions we can do the activity by making figures of unknown sides by assuming it in the form of x, y.so that we can find the known values.

Answer 2 :-

The best way of solving the above questions is that it is already given in the question that the beam is symmetrical so, here we can use similarity theorem.

Answer 3 :-

It necessary to learn about trapezoid and it's properties because if we don't know the properties and what is trapezoid then we will not be able to answer the given question.

Some properties of trapezoid

Answer 4 :-

Well, The answer is very easy that if we don't know anything regarding the trapezoid then we will not be able to any question based on it and if we have incomplete knowledge about it then we will able to solve it but we always got incorrect answers most probably.

Answer:

True, it is a solution

Step-by-step explanation:

First, let’s distribute 1/3 to x and 4

When we do this, we get:

1/3x+4/3=20

Now, we can solve the equation!

Subtract 4/3 from each side of the equation to isolate the x

We now have 1/3x=18 2/3

Now we divide 1/3 on each side to isolate the x (this is the same as multiplying by 3/1 on each side)

This gets us to x=56

So it is true

Leonardo purchases goods at the store of 30.894 and paid $30. 89. Leonardo did not pay enough.

Percentage of a number is the part of the number expressed in the in every hundred. Percentage of a number is expressed with the symbol '%'.

Leonardo makes the following purchases at the

Store: 1 backpack for $16.89, 5 spiral notebooks for $1.19, each 1 pack of mechanical pencils for $3.68, 2 packs of lead refills for $1. 88 each

The total amount of these items is,

[tex]P=1\times16.89+5\times1.19+1\times3.68+2\times1.88\\P=16.89+5.95+3.68+3.76\\P=30.28[/tex]

The coupons are applied after tax, and the sales tax is 5% of the purchase. Thus the amount will be,

[tex]P=30.28+30.28\times\dfrac{5}{100}\\P=31.794[/tex]

Leonardo has 2 coupons, each for 45 cents off on the purchase of a pack of lead refills. Thus, the sum become,
