Answer:
23
Step-by-step explanation:
The picture shown is a unfolded rectangular prism.
The formula to find the surface area of a rectangular prism is:
A = 2(WL+HL+HW)
(W = width, L = Length, H= Height)
So we would need to determine the Height, Length, and Width first, and then plug them into the formula and solve for the area.
In this case:
The height is: 4 cm
The length is: 10.5 cm
The width is: 6.4 cm
Now that we have determined the height, length, and width, we simply plug them into the formula I showed earlier.
In this case the answer would be 269.6.
D. 269.6
Answer:
Step-by-step explanation:
731² - 631² is the difference of squares.
731² - 631² = (731+631)(731-631) = 1362×100
therefore, 731² - 631² is divisible by 100
Answer:
= 85
Step-by-step explanation:
given m = - 2, and n = -4
Substitute the given values into the polynomial expression:

![[(-2)^{4} + 5] - (-4)^{3}](https://tex.z-dn.net/?f=%5B%28-2%29%5E%7B4%7D%20%2B%205%5D%20-%20%28-4%29%5E%7B3%7D)
= (16 + 5) - (-64)
= 21 + 64
= 85
Therefore, the correct answer is 85.
