Answer:
The value of x is 49 and the value of AB is 90
Step-by-step explanation:
You know that AB and DE are congruent. That information is given to you.
You set the equations equal to each other and then solve.
2x - 8 = x + 38
Subtract x
x - 8 = 38
Add 8.
x = 49
Plug back into 2x - 8 to find the value of AB
2 times 49 - 8
98 - 8
90
Answer:
x = 45
Step-by-step explanation:
Corresponding sides of similar triangles will be in same ratio.
![\dfrac{x}{x+18}=\dfrac{20}{28}](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%7D%7Bx%2B18%7D%3D%5Cdfrac%7B20%7D%7B28%7D)
Cross multiply
x*28 = 20*(x+18) {Use distributive method}
28x = 20x + 360
28x - 20x = 360
8x = 360
x = 360/8
x = 45

what is wrong with you bro
Answer:
240 cm^3
Step-by-step explanation:
Volume of a rectangular prism = base area x height
the base is a rectangle, thus base area = width x length = 4 x 5 = 20 cm^2
20cm^2 x 12 = 240 cm^3
