Answer:
13/6
Step-by-step explanation:
first you have to make a common domainer you do this by muiplying one of them by 2 and the other one by 3 and that makes a common domainer of 6 which you can do 22-9 and u get 13 then you put the 13 over the 6 and u get 13/6
I really do not get it . It’s this a question ? If so can you be a little more specific .
Yes you’re almost there the answer is negative 9
Answer:
Here x varies directly with y
If y= 16 then x= -8
So, when y = -14
then x = -8× -14/16
= 14/2
= 7
Answer: 4x2 + 32x − 80 = 0
Step-by-step explanation:
Area of a rectangle is given by
A = l*w
The length is (2x+10) and the width is (2x+6)
A = (2x+10)(2x+6)
FOIL
first 2x*2x = 4x^2
outer 2x*6 =12x
inner 2x*10 =20x
last 10*6=60
Add this together
4x^2 +12x+20x +60 = 4x^2 +32x+60
This must equal 140 inches
4x^2 +32x+60 = 140
Subtract 140 from each side
4x^2 +32x+60-140 = 140-140
4x^2 +32x -80=0
