Answer:

see below

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles.

139 = <Q + <P

= 6y+1 + 4y+8

= 10y+9

139 = 10y+9

Subtract 9 from each side

130 = 10y

Divide each side by 10

13 = y

<P = 4y+8 = 4*13+8 = 60

<Q = 6y+1 = 6*13+1 =79

QPR = We know this makes a straight line with 139

= 180-139 = 41

What is the factored form of a2 – 121?

Flura [38]

Answer:

The factored form $a^2-121$ is $(a+11)(a-11)$ .

Step-by-step explanation:

Given : $a^2-121$

We have to write the given expression in factored form.

Factor form of an expression is writing the expression in lower power form such that the product of factors given the original expression

Consider the given expression $a^2-121$ .

We know the algebraic identity $x^2-y^2=(x+y)(x-y)$

Here $a^2-121=a^2-(11)^2$ .

Comparing with identity stated above , we have x= a , b = 11 , thus, we get

$a^2-(11)^2=(a+11)(a-11)$ .

Thus, the factored form $a^2-121$ is $(a+11)(a-11)$ .

A contractor is building a circular swimming pool. The radius of the circle 12 feet. He needs to know the circumference in order

dolphi86 [110]

C=Pi X D
Diameter is twice the radius so that would be 24 feet

C = Pi X 24
C = (22/7) X 24
C = 75.428 Feet.
