Part A)
Using the Pythagorean theorem you can find the height:
17^2 = 8^2 + x^2
289 = 64 +x^2
x^2 = 289 - 64
x^2 = 225
x = √225
x = 15
The height is 15 cm.
Part B)
Area of the triangular side: 1/2 x 16 x 15 = 120 square cm.
There are two triangles so 120 x 2 = 240 square cm.
One side = 20 x 17 = 340
There are 2 sides so 340 x 2 = 680 square cm.
The bottom is 16 x 20 = 320 square cm.
Total cardboard needed: 240 + 680 + 320 = 1,240 square cm.

Answer:
440 or 490
Step-by-step explanation:
I'll just assign a value of x and solve it so that I'll be able to arrange them in order from greatest to least.
I am assuming that x = 2.
4x + 9 ⇒ 4(2) + 9 = 8 + 9 = 179^x + 1 ⇒ 9² + 1= 81 + 1 = 82x² + 3 ⇒ 2² + 3 = 4 + 3 = 74x ⇒ 4(2) = 89^x ⇒ 9² = 81x² ⇒ 2² = 4
based on my assumption, the order from greatest value to least value is:1) 9^x + 12) 9^x3) 4x + 94) 4x5) x² + 36) x²
