Answer:
Step-by-step explanation:
Each of the squares has trinomials that factor. x^2 - 14x + 49 = (x - 7)^2
When you take the square root (to get the side length) you get x - 7. So the length of each square is x - 7) = 0;..........x=7 That's the answer to a.
The answer to b is the same. The width =7
It's a square both sides have to be equal.
The length of the rectangle when the two squares are put together is 7 +7 = 14.
Answer: Question a = 7..... Question b = 7 ......... Question C = 14
Speed = distance / time

4213
Step-by-step explanation:
go to the numbers that pop out and do it backwards.
Answer: x=1
y=2
Step-by-step explanation:
y=-x+3
y=4x-2
-----------
y=y
-x+3=4x-2
3+2=4x+x
5=5x
x=1
y=-1+3
y=2
