Answer:
y = ± sqrt(x+7)
Step-by-step explanation:
y = x^2 -7 solve for 'x' .... add 7 to both sides
y+7 = x^2 sqrt both sides
+- sqrt(y+7) = x switch 'x' and 'y'
y = +- sqrt(x+7)
Answer:
40.24922.........
Step-by-step explanation:
For a cylindrical tank, volume = πr²h
Where r = radius = diameter/2 = 6/2 = 3m
height , h = 3m
Volume = 3.14 * 3² * 3 = 84.78
Volume ≈ 84.8 m³
Option D.
Answer:
5(2x+5)
Step-by-step explanation:
This is the answer because the highest multiple is 5 for both of them.
so since it is 5 divide both numbers by 5 put 5 outside the parenthisis and
then divide the numbers inside
this will give you - 5(2x+5)
Hope it helps :)
Answer:
18x + 16
Step-by-step explanation:
2 x length + 2 x width = perimeter
2(5x + 2) + 2(4x + 6)
= 10x + 4 + 8x + 12
= 18x + 16
