Starting with 113+ (2x+5)=180, combine like terms and to get 118+2x=180. Subtract 180-118, which gives you 62. Then you have 2x=62. Divide both sides by 2 to get a final answer of x=31.
Answer:
Option (D)
Step-by-step explanation:
Surface area of a square pyramid is determined from the formula,
Surface area = Area of the square base + 4(Area of one lateral triangular side)
Area of the base = (Side)²
= 8²
= 64 cm²
Area of one lateral triangle = ![\frac{1}{2}(\text{Base})(\text{Height})](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%28%5Ctext%7BBase%7D%29%28%5Ctext%7BHeight%7D%29)
= ![\frac{1}{2}(8)(8)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%288%29%288%29)
= 32 cm²
Therefore, surface area of the square pyramid = 64 + 4(32)
= 64 + 128
= 192 cm²
Therefore, Option (D) will be the correct option.

Answer:
![x^{-28}*7^{-56}](https://tex.z-dn.net/?f=x%5E%7B-28%7D%2A7%5E%7B-56%7D)
Step-by-step explanation:
Firstly, you need to know that raising a fraction to a power raises both the top and the bottom to that power.
Second, a negative power on the top and bottom flips the fraction
Last, raising a power to a power multiplies the powers
So,
=
=
=![x^{-28}*7^{-56}](https://tex.z-dn.net/?f=x%5E%7B-28%7D%2A7%5E%7B-56%7D)
