Answer:
k = -1, -2.
Step-by-step explanation:
4k^2+12k+8 = 0
Divide by 4:
4(k^2 + 3x + 2) = 0
4(k + 1)(k + 2) = 0
k = -1, -2.
Answer:
<u>3/5</u>
Step-by-step explanation:
= 2/3 + 2/5 - 7/15
= 10/15 + 6/15 - 7/15
= 9/15
= <u>3/5</u>
First we subtract the whole numbers:
6-5=1
Now we subtract 2/8 from 3/8:

.
Your answer is:
Width=w
length=l
w+2=l
2(w+l)=88
2(w+w+2)=88
2(2w+2)=88
4w+4=88
4w=84
w=21
21+2=23
The length of a rectangle if the perimeter is 88 inches and the length is 2 inches more than the width is 23.
