Step-by-step explanation:
x + 5(x + 2)
Distribute
x + 5x+10
Combine like terms
6x+10
Let x = 9
6(9) +10
54+10
64
Answer and explanation :
We have given that the expression 
We have to prove L.H.S = R.H.S
Lets take L.H.S
It can be written as 
( As in multiplication exponent are added )
So 
= R.H.S
Hence proved
Answer:
x = 72
Step-by-step explanation:
For all polygons, the exterior angles add up to 360°
Since a pentagon has 5 exterior angles, you do
angle = 360 ÷ 5 = 72
here's a picture so you understand better
Answer:
65 degrees
Step-by-step explanation:
y is a right angle and a is 30 degrees. this means that the supplementary engle of x is 45 plus 70 which is 115. 180-115 = 65 degrees.
If you have a whole dollar then split it up into quarters. 4 quarters is 1 dollar. so take one quarter (25¢) So decimal from would be .25
faction form would be 1/4. beacuse if you multiple .25 × 4 it would be 1. and multiple
1/4 × 4/1 it would be 4/4 which equal 1
