Answer: -5 < x < 3
Step-by-step explanation:
Subtract 6 from both sides of the equation (-4 and 12, with a result of -10 < x < 6) and then divide by two on both sides (with the result being the answer.
√(x²+13)=2+x
[√(x²+13)]² = (2+x)²
x²+13=4+4x+x²
x²-x²-4x=4-13
-4x=-9
x=-9/-4
x=9/4
To check:
√(x²+13)=√(81/16 +13)=√[(81+208)/16]=√(289/16)=17/4.
2+x=2 + 9/4=(8+9)/4=17/4
Answer:
391
Step-by-step explanation:
406 (from top) - 15 (50% exposure)= 391
Answer:
12
Step-by-step explanation:
Alr so correct me if I'm wrong but I think you made a mistake. It says find 44 of those rectangles. You found just 1 in that case which the area is 3/11. You have to do 3/11 X 44 which is
3/11 x 44/1 = 132/11 = 12.
As I said, correct me if I'm wrong.
Hope this Helps!
