<span>So, L*W=A Because it is 4 cm longer, L=W+4 Because the area is 96, LW=96 Substitute to get W(W+4)=96 Multiply it out. W^2+4W-96=0 By solving the quadratic, W+12(W-8)=0 so either W+12 or W-8 is zero. The width must be positive, so the width is 8. Therefore the length is 12.
Hope this helps.</span>
I believe the answer is X=15
Answer:
1. Evaluate 3y - 4 for y =5
3*(5)-4=15-4=11
2. 65 + x = 99 x = ?
65+x=99
x=99-65
x=34
3. Find the product. 38.7 *21
38.7*21=812.7
4. Which value satisfies the equation? 9x + 3 = 30
The right value for x would be:
9x+3=30
9x=30-3
9x=27
x=27/9=3
Step-by-step explanation:
Answer: Should be rational
hope this helps.
66 is the answer
76+ 38= 114
114+ 66 = 180
