Since x is the length, then x+7 has to be the width.
The area of a rectangle can be found via the formula :
A = length * width
So if we replace the area with the given number (170) and the length, and width, with what we assumed, we get..
170 = x * (x+7)
[which is.. ]
170 = x^2 +7x
0 = x^2 +7x - 170
And that is the answer.
Answer:
Yes; Tina could have won 12 games because 2x + 5 = 29.
Step-by-step explanation:
Let
x ----> the number of games that Tina has won
y ---> the number of games that Maryann has won
we know that
-----> equation A
----> equation B
substitute equation A in equation B and solve for x





so
The number of games that Tina has won is 12
Answer:
Step-by-step explanation:
x²-16x+60
=x²-6x-10x+60
=x(x-6)-10(x-6)
=(x-6)(x-10)
so dimensions are x-6 and x-10.
