Challenge is 40!


How we know 5 plus 5 equals 10 plus another 5 equals 15!

if you put 2 8’s together you can get 16!

if you times 6 by ten it adds a 0 at the end leaving you with 60

last one 10 plus 10 plus 10 plus 10 equals 40 which is equivalent to 8 times 5!

Solve for x math question
Colt1911 [192]

Square both sides

9(x + 2) = x + 4

Expand

9x + 18 = x + 4

Subtract x from both sides

9x + 18 - x = 4

Simplify 9x + 18 - x to 8x + 18

8x + 18 = 4

Subtract 18 from both sides

8x = 4 - 18

Simplify 4 - 18 to -14

8x = -14

Divide both sides by 8

x = -14/8

Simplify 14/8 to 7/4

<u>C. x = -7/4</u>

What is the area of the irregular figure below?
andrey2020 [161]

Answer:

B, 48 inches

Step-by-step explanation:

First calculate the area of the parallelogram: 4 x 6

4 x 6 = 24

Then calculate the area of the triangle: 4 x 6

4 x 6 = 24

Then you add the two areas: (4 x 6) x 2 or 24 x 2

24 x 2 = 48

Therefore, your answer is B, 48 inches
