Answer:
x=-2
Step-by-step explanation:
Let x=L.
Then let 3x+2=W
Giving you 124=(x)+(x)+(3x+2)+(3x+2)
Then simplify and solve.
124=8x+4
124-4=8x
120=8x
120/8=x
15=x
Then put that value back into the original equations to find the dimensions.
x=L
15=Length
and
3x+2=W
3(15)+2=W
77=Width
<span>2k² = 9 + 3k
⇒ </span><span>2k² - 9 - 3k
= 0
⇒ 2k² - 3k -9 = 0
b² - 4ac = 3² - 4*2*(-9) = 81>0
It has 2 real roots.
