Answer: x = 7 or x = -8
x² + x - 56 = 0
⇔ x² + 8x - 7x - 56 = 0
⇔ x(x + 8) - 7(x + 8) = 0
⇔ (x - 7)(x + 8) = 0
⇔ x - 7 = 0
or x + 8 = 0
⇔ x = 7 or x = -8
Step-by-step explanation:
A mixed number is one that has an integer along with a proper fraction, so that would be (for this improper fraction):
50/12 = 4 1/6
12 goes into 50, 4 times with a remainder of 2
you get: 4 and 2/12, but 2/12 can be reduced further to 1/6
so that's how i got the answer of 4 1/6
Hey there!
Okay let's get cracking :D
The equation is.... (2x/3) - 6 = 9
2x/3 = 15
2x = 45
<u>x = 22.5</u><u /> <----- And that is your answer!
I hope it helped!

The ratio is 1 to 68.8 or 1 : 61.8 and you're looking for 6 : x so all you have to do is multiply 61.8 by 6 and you get 370.8
A=WL
P=2(L+W)
A=(x)(14-x)
W=x
L=14-x
P=2((14-x)+x)
P=2(14-x+x)
P=2(14+0)
P=2(14)
P=28
perimiter=24 units
