Answer:
x=1
Step-by-step explanation:
We distribute the negative 5 to x minus three to get 8x-5x+15=18. Then, we cancel out the 15 by subtracting it from both sides. This leaves us with 8x-5x=3. When we subtract, we get 3x=3, and when we divide both sides by 3, we get x=1. Hope this helps :)
Answer:
x = 12
Step-by-step explanation:
42 + 4x = 90 ( as it is right angle)
transpose to find x
4x = 90 - 42
4x = 48
x = 48/4
x = 12
Answer: Option A. -4x^8
Step-by-step explanation:
The polynomial function given in the graph has 4 real roots. And because the graph falls to the left and right, it will have even order and negative leading coefficient.
So we have only one option that matches the required conditions, and i.e. option A.
Answer:
36m
Step-by-step explanation:
If the area of a square is 81 m
A=81m
but we know that A=l² so l=radA
l=9m
p=4l
finally p=4•9=36m
