Answer:
Step-by-step explanation:
1) the two members of the expression has 4x in common, so we can rewrite it as: 4x(3x-2)
2) we have to find two numbers that multipied give -36 and that added up give 5
the two number are 9 and -4
we can rewrite the expression as : (x+9)(x-4)
3) we have to solve the associated equation
3x^2+10x+8 = 0
Δ/4 = 25-24 = 1
x1 = (-5+1)/3 = -4/3
x2 = (-5-1)/3 = -2
now we can rewrite the expression as
3(x+4/3)(x+2) = (3x+4)(x+2)
Answer:
1. 12x^2-8x
taking common 4x
4x(x-2)
2. x^2+5x-36
doing middle term factorization
x²+9x-4x-36
x(x+9)-4(x+9)
(x+9)(x-4)
3. 3x^2+10x+8
Doing middle term factorization
3x²+6x+4x+8
3x(x+2)+4(x+2)
(x+2)(3x+4)
A cafeteria manager can choose from among six side dishes for the lunch menu: applesauce, broccoli, corn, dumplings, egg rolls, or French fries. He uses a computer program to randomly select three dishes for Monday’s lunch.
Answer:
0.20
Step-by-step explanation:
Given : The number of side dishes for the lunch menu =6
The number of ways to select 3 dishes from 6 :
Total outcomes :
If applesauce and broccoli is already selected , then we need to select only one dish out of remaining 4 dishes.
Number of ways to select 1 dish from 4 :
Favorable outcomes:
Now, the theoretical probability that applesauce and broccoli will both be offered on Monday :-
Hence, the theoretical probability that applesauce and broccoli will both be offered on Monday = 0.20

Answer:
LA = 120 sq cm
SA = 132 sq. cm.
Step-by-step explanation:
LA = ph where p = perimeter of the base and h = the height of prism.
Your base is a triangle. The third side = [tex]\sqrt{5^{2} - 3^{2} }[/tex] = [tex]\sqrt{25 - 9} = \sqrt{16} = 4[/tex]
Now, the perimeter of the triangle is 3 + 4 + 5 = 12
So, LA = 12(10) = 120 sq cm
The area of the base is the area of a triangle. A = bh/2 = 4(3)/2 = 6
SA = 2B + LA where B is the area of the base
SA = 2(6) + 120 = 12 + 120 = 132 sq. cm.

Kathryn puts some red, white, blue and pink counters in a bag. She gives the bag to
Clive, who takes a counter out at random, records the colour, and then puts it back
After some time Clive concludes that the probabilities for each colour are
red: 36% white: 34% blue: 3
Kathryn tells him there are fewer than 100 counters in the bag.
Work out how many counters of each of the colours are in the bag.

Zoey takes out a loan of $25,000 to pay for a car. Her interest rate is 3% for 60 months. How much will Zoey pay in total for the car?
Answer: $28750
Step-by-step explanation:
Since 12 months = 1 year, it should be noted that 60 months = 60/12 = 5 years.
Simple interest = Principal × Rate × Time
= $25000 × 3% × 5
= $25000 × 0.03 × 5
= $3750
The total amount that Joey will pay for the car will be the value of the principal plus the interest which will be:
= $25000 + $3750
= $28750
A veterinarian office conducted a survey of the weight of dogs that came in for physicals. 55, 37, 8, 50, 60, 50, 48 Find the mean:
Answer:
44
Step-by-step explanation: mean is the average so add 55, 37, 8, 50, 60, 50, 48 and you get 308 then divide 308 by how many numbers you added which is 7, so 308 divided by 7 is 44 which is the answer

Find the distance between the points (1,–5) and (9,9).
Answer:
[tex]\sqrt{260\\[/tex] or 16.12
Step-by-step explanation:
distance formula is [tex]} d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}[/tex]
Distance (d) = √(9 - 1)2 + (9 - -5)2
= √(8)2 + (14)2
= √260
= 2√65
= 16.124515496597
What should be done first to evaluate the expression?
6 + 8 ÷ 4 + (4 × 5)²
Answer:
First, follow the first step in PEMDAS so you would do the parenthesis first followed by exponents, multiplication, division, addition, then subtraction
Step-by-step explanation:
6 + 8 ÷ 4 (4*5)^2
6 + 8 ÷ 4 + 20^2
6 + 8 ÷ 4 + 400
6 + 2 + 400
= 408

Triangle ABC is similar to DEF. Which proportion can be used to find the length of DE in centimeters?
Answer:
[tex]\frac{DE}{4} = \frac{9}{3}[/tex]
[tex]DE = 12[/tex]
Step-by-step explanation:
Given
See attachment for triangles ABC and DEF
Required
The proportion to find DE
To solve for DE, we can make use of the following equivalent ratios;
[tex]AB:DE = BC:EF[/tex]
Substitute values for AB, BC and EF
[tex]4:DE = 3:9[/tex]
Express as fractions
[tex]\frac{DE}{4} = \frac{9}{3}[/tex]
The above is the proportion to solve for DE
Solving further:
[tex]\frac{DE}{4} = 3[/tex]
[tex]DE = 4 * 3[/tex]
[tex]DE = 12[/tex]
which sets of three lengths can be used to form a triangle?
A. 7ft, 5ft, 2ft

Find the measure of angle x. Hint. The sum of the measures of the angles in a triangle is 180 degrees.
A. 6°
B. 90°
C. 180°
D. 86°
Answer:
D
Step-by-step explanation:
Básicamente sumas esos 2 y se lo restas a 180.
Answer:
D. 86
Step-by-step explanation:
since the angles of a triangle add up to equal 180, all you have to do is add the angles you know and then find the one you don't by subtracting it from 180.
this is how it looks mathematically:
180=26+68+x
180=94+x
180-94=x
x=86
