Answer:
B) b=13
Step-by-step explanation:
13-4x is the same as -4x+13
The square has area 8*8=64, the rectangle has area 7*4=28, and the triangle has area 7*6/2=21. Their sum is 64+28+21=113.
Answer:
The input is zero, the output is -1
Step-by-step explanation:
We want to know the y value when the x value is zero
When x =0, y = -1
The input is zero, the output is -1
Question :
5m^2 - 29m + 20
Steps:
What can u factor to get 20?
you can make 5 and 4 to make 20 so,..
1. Break it into groups
(5m^2 - 4m) + (-25m + 20)
*Factor out m from (5m^2 - 4m) : m(5m - 4)
*Factor out -5 from (-25m + 20) : -5(5m - 4)
2. Then, you can factor out the common term : (5m - 4) because they both have it. And then u would move the m by the -5 so,...
= (5m - 4)(m - 5) <======= <em>Answer</em>
Hope this helped!!!

Since x represents the year, year 15 will be 15 years.
Plug in "15" as your "x"
y = -2(15)^2 + 36(15) + 6
15^2 = 225 (Exponents come before multiplication)
y = -2(225) + 36(15) + 6
y = -450 + 540 + 6
y = 90 + 6
y = 96
<em>The answer is B</em>
