Step-by-step explanation:

Since ABC is an equilateral triangle each <=60

Now Givin ac=cd so <cda

Answer:

It is a right angled triangle

Step-by-step explanation:

Left hand side (LHS) = 15²

= 225cm

right hand side (RHS) = 12²+9²

=225

LHS = RHS so it is a right angled triangle

Answer:

thats not a right angle triangle that is scalene triangle

First box would be 288, second 351, third on the bottom would be 212, forth on the bottom would be 99 right?

Step-by-step explanation:

Well, its there already, I assume just placed differently?

Answer:

See below

Step-by-step explanation:

You cannot find two whole number integers that give a sum of -12 and a product of 6.

-1 + -11 = -12, but (-1)(-11) = 11, which isn't 6

-2 + -10 = -12, but (-2)(-10) = 20, which isn't 6

...and so on...

x² - 12x + 6

This is in the form of ax² + bx + c.

We can not factorize because b < ac.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

x² - 12x + 6

This is in the form of ax² + bx + c.

Middle-term factorization.

We can not use middle-term factorization because b < ac.

Where a = 1, b = -12 and c = 6

Now,

Using determinant.

x² - 12x + 6

It is in the form of ax² + bx + c

a = 1, b = -12, and x = 6

So,

x = -b ± √(b² - 4ac) / 2a

x = 12 ± √(144 - 24) / 2

x = 12 ± √120 / 2

x = 12 ± 2√30 / 2

x = 6  ± √30

x = 6 + √30 and x = 6 - √30

Thus,

The solutions are x = 6 + √30 and x = 6 - √30.

Step-by-step explanation:

2/6 * 3/5

make like denominators

10/30 * 18/30

or you can do it decimals

2/6 is .3333 repeating. and 3/5 is .6 and you would get .2 which is equivalent to 6/30

Step-by-step explanation:

two times five eigths would be 1.25. Or 1 1/4 or 5/4. If you times both the denominator and numerator by two, you would get 10/8. 18/8=1.25

Answer:

10/8 or 1 2/8 ( mixed number )

Step-by-step explanation:

First, turn the two into 2/1 and then multiply

2/1 by 5/8

start by multiplying

2 x 5 =

which is equal to 10 and you keep 8 the same because 1 x 8 is 8

then you get your answer of 10/8

But if you want it to be a  mixed number then the final answer will be

= 1 2/8 ( mixed number )

Answer:

[A] The difference in height between the pelican and the heron is -33 feet.

[E] The difference in height between the pelican and the trout is 40 feet.

[F] The distance between the heights of the pelican and the trout is 40 feet.

Step-by-step explanation:

Note: 0 the sea level.

Since the heron is perched in a tree 50 feet above sea level and directly below the heron the pelican is flying 17 feet above sea level, you can find the difference in height between the pelican and the heron by subtracting 50 feet from 17 feet.

Then, you get that this is: 17-50= -33 feet

Now, according to the information given in the exercise, you know that the trough is swimming directly below them and its height is 23 feet below sea level. If you represent this with an integer, this is: -23

Therefore you can find the difference in height between the pelican and the trout through the following subtraction:

17-(-23)=17+23=40  feet.

Hence, distance = 40 feet.

Answer:

x = 10

scalene, obtuse

Step-by-step explanation:

Sum of interior angles of a triangle = 180°

⇒ 10x + 8 + 52 + 2x = 180

⇒ 12x + 60 = 180

⇒ 12x = 120

⇒ x = 10

∠A = 52°

∠B = (10 x 10) + 8 = 108°

∠C = 2 x 10 = 20°

Scalene:   no equal sides (and no equal angles)

Obtuse:   one of the interior angles is bigger than 90°

Answer: To find the area for a parallelogram use the formula A=bh

Step-by-step explanation:

The area of the parallelogram is 32cm.

Since the area of the parallelogram equals base times height, you have to find the base of the parallelogram which, is 8, and then find the height, which is 4.

Then multiply them to get your answer.

Base = 8

Height = 4

8cm x 4cm = 32cm

So, the area of the parallelogram is 32cm.
