Answer:
X = 51
Step-by-step explanation:
24 + 27 = 51
x - 27 =
51 - 27 = 24
Answer:Yes may I know what answer you are trying to explain?
Step-by-step explanation:
Area of semicircle is given by:

r is the radius, and we are given the diameter. Radius is half the diameter, so it's 2.5m. Let's plug that into the formula (using 3.14 as an estimation for pi):

So, the area of this semicircle is
9.81m².
14 I think.You would subtract 15-8 which is 7 and then add 7 which is 14
Answer:
Step-by-step explanation:
16 = 2 *2 * 2 * 2 = 2⁴
16y⁴ = (2y)⁴
x⁴ - 16y⁴ = x⁴ - (2y)⁴
= (x²)² - [ (2y)² ]²
{Use identity = a² -b² =(a +b)(a- b). Here a =x² & b =(2y)²}
= (x² + (2y)² ) (x² - (2y)² )
= (x² + 4y²) (x² - 4y²)
