7x-4=31
7x=31+4
7x=35
x=35/7=5

4y+8=24 
4y=24-8
4y=16
y=16/4=4

Hence, x=5;y=4

Answer:  x=5 and y=4

Step-by-step explanation:

From the given picture, it can be seen that the coressponding sides of the triangles are equal such that 7x-4=31\\\\\Rightarrow7x=35\\\\\Rightarrow x=\frac{35}{7}\\\\\Rightarrow x=5

Also, 4y+8=24\\\\\Rightarrow\ 4y=24-8\\\\\Rightarrow\ 4y=16\\\\\Rightarrow\ y=\frac{16}{4}\\\\\Rightarrow\ y=4

Therefore, the value of x =5 and the value of y =4.

<h3>Answer: 24 (choice C)</h3>

Assuming M is a midpoint of KW, this means that WM and KM are congruent

WM = KM

x+3 = 2(x-3) ... substitution

x+3 = 2x-6

2x-6 = x+3

2x-6-x = x+3-x .... subtract x from both sides

x-6 = 3

x-6+6 = 3+6 ... add 6 to both sides

x = 9

Use x = 9 to find the length of WM

WM = x+3 = 9+3 = 12

Which can be used to find the length of KM as well

KM = 2(x-3) = 2(9-3) = 2(6) = 12

both lengths are the same (12) as expected

This makes WK to be

WK = WM + KM

WK = 12 + 12

WK = 24

This for composite figures
Vinil7 [7]

Answer:

  114 square meters

Step-by-step explanation:

The figure decomposes into two congruent trapezoids, each with bases 15 m and 4 m, and height 6 m. The area formula for a trapezoid is ...

  A = 1/2(b1 +b2)h

__

Each trapezoid will have an area of ...

  A = 1/2(15 +4)(6) = 57 . . . . square meters

The figure's area is twice that, so is ...

  figure area = 2 × 57 m² = 114 m²
