The answer is 13.76 sq inches first you find the area of the plywood 8x8=64 then you minus the area of the circle cut out. So that formula is pir^2 and that is 3.14x16=50.24 now minus it off plywood area 64-50.24=13.76 square inches
We are asked to simplify the given mathematical expression a5*3b9*6a. To do this, we need to follow the law of exponent that if it is same variable being multiplied we can add the power. In this problem, variable "a" existed twice so we can add powers of a5 to 6a such as:
6a(5+1) *3b9
6a6*3b9 , then multiply constants which are 6 and 3
18a6b9
The answer is 18(a^6)(b^9).
It is 5, I hope this answers your question
Answer: 20
Step-by-step explanation:
Assuming your question is:
Z² - X² - XY X = -2, Y = 3, Z = -4
Substitute values
(-4)² - (-2)² - {(-2)(3)}
{(-4)(-4)} - {(-2)(-2)} - (-6)
(16) - (4) + 6
16 - 4 + 6
