Answer:
BC = 20
Step-by-step explanation:
AC = AB + BC
28 = x-10 + x+2
Combine like terms
28 = 2x -8
Add 8 to each side
28+8 = 2x-8+8
36 = 2x
Divide by 2
36/2 = 2x/2
18 =x
We want to find BC
BC = x+2
=18+2
=20
We have the expression 4(x + 8) + 5(x - 3).
First, expand the parentheses by using the distributive property.
4(x + 8) + 5(x - 3) = 4x + 32 + 5x - 15
Now combine like terms.
4x + 32 + 5x - 15 = 9x + 17
So, C 9x + 17 is the answer.
Based on the lengths, the cheerleaders' banner is scaled down by a factor of 4.
So, 44 ÷ 4 = 11.
For the perimeter, 156 ÷ 4 is 39.
For the area, you have to do A=bh
(Area = base × height)
The base (length) is 11 inches, multiply that by two to get 22 inches which is the amount for both lengths. If the total perimeter is 39, you have to subtract 22 from that to get the remaining inches which is 17.
17÷2= 8.5 inches. The height is 8.5.
Now you can plug them in
A=bh
A=(11)(8.5)
A=93.5 in^2
The final answer is:
Area = 93.5 in^2
Length = 11 in
Perimeter = 39 in
I hope that helps!
40+60+y=180
y=180-100
y=80
A triangle is 180° so you add all the numbers available in the trianle and minus it with 180 to see what is left from the 180 and that will be the inner angle answer
X=180-80=100
A straight line is also 180° so if u minused one side which in our case is 80 u will get the rest which is the outer angle
