I need help on 25 please help none of my family members understand this part of math I have no older siblings so I am on my own when it comes to math this must be done this evening. Please I beg you someone please help me I’m desperate. Also please explain how you got to the answer .

A=2

Step-by-step explanation:

6a+18a=6a+10a+16 (cancel equal terms)

18a=10a+16 (move variable to left)

18a-100a=16 (Collect like terms)

8a=16 (Divide both sides)

Hope This Helps :)

A = 2

Step by step solution :

STEP

1

:

Equation at the end of step 1

(6a • (a + 3)) - (2a • (3a + 5) + 16) = 0

STEP

2

:

Equation at the end of step 2

6a • (a + 3) - (6a2 + 10a + 16) = 0

STEP

3

:

STEP

4

:

Pulling out like terms

4.1 Pull out like factors :

8a - 16 = 8 • (a - 2)

Equation at the end of step

4

:

8 • (a - 2) = 0

STEP

5

:

Equations which are never true:

5.1 Solve : 8 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

5.2 Solve : a-2 = 0

Add 2 to both sides of the equation :

a = 2

One solution was found :

a = 2

idk lol xd

step-by-step explanation:

ez do it yourself lazy

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
