Answer:
L = 3x - 2
P = 6x - 10
Step-by-step explanation:
Area = length * width
A = l*w
so if the width is 6 inches we can say w = 6
and we can say that l = to the length of the rectangle
if we substitute this:
(18x - 12) = l * 6
we get the answer l = 3x - 2 since we divide both sides by 6.
the expression for length of the rectangle is -> l = 3x - 2
for the perimeter:
P = 2(l + w)
if we substitute this:
P = 2(3x - 2) + 6
distributive property:
P = 2(3x) - 2(2) + 6
then would be:
P = 6x - 4 + 6
(combine like terms) -> P = 6x - (4 + 6)
then you would get: P = 6x - 10
which can also be writtern as -> P = 6x + (-10)
but this is not simplified so you would just write it as 6x - 10

Answer:
1670.8 cm³
Step-by-step explanation:
Volume of square Pyramid = ⅓*a²*h
h = 15.3 cm
a = 18.1 cm
Plug in the values
Volume of the pyramid = ⅓*18.1²*15.3
Volume = 1670.81 ≈ 1670.8 cm³ (nearest tenth)

Answer:
The price of a medium pizza with 3 toppings is $15.
Step-by-step explanation:
If "t" represents the number of toppings, you will use the expression "9+2t" and plug in 3 for t (since there are 3 toppings)
So it will look like:
9+2(3)
Then you're gonna use PEMDAS, multiply 2*3
9+6
And then you get an answer of $15
Hope this helps :))
Answer:
Part 1) m∠EFG=94°
Part 2) m∠GFH=86°
Step-by-step explanation:
we know that
m∠EFG+m∠GFH=180° -----> by linear pair (given problem)
we have
m∠EFG=3n+22
m∠GFH=2n+38
substitute the values
(3n+22)°+(2n+38)°=180°
Solve for n
(5n+60)=180
5n=180-60
5n=120
n=24
<em>Find the measure of angle EFG</em>
m∠EFG=3n+22
substitute the value of n
m∠EFG=3(24)+22=94°
<em>Find the measure of angle GFH</em>
m∠GFH=2n+38
substitute the value of n
m∠GFH=2(24)+38=86°
