What is the missing coefficient of the x-term of the product (-x-5)2 after it has been simplified?

The missing coefficient of the x-term of the product (-x-5)2 is 10.

Step-by-step explanation:

Through whole square formula.

(-x-5)2 = (-x)^2 -2(-x)(5)+(5)^2

=x^2+10x+25

Therefore, the missing coefficient of the x-term of the product is 10

10

Step-by-step explanation:

The given expression is

We need to find the coefficient of x.

According to the property of algebra.

In the given expression a=-x and b=5.

Substitute a=-x and b=5 in the above formula.

On further simplification we get

Coefficient of x is a multiplicative factor of x.

Therefore, the coefficient of x is 10.

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

step-by-step explanation:

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
