T=34xP
T= tip for him
P= percent he charges for tip
Area of a parallelogram=base x heigth
Data:
base=(2x+3)
heigth=(ax+5)
area of this parallelogram=8x²+bx+15
Therefore:
8x²+bx+15=(2x+3)(ax+5)
8x²+bx+15=2ax²+10x+3ax+15
8x²+bx+15=2ax²+(10+3a)x+15
Then:
8x²=2ax²
a=(8x²)/(2x²)=4
bx=(10+3(4))x
bx=(10+12)x
b=22x/x=22
Answer: a=4 and b=22.
Which Michael?? There are many many many Michaels in the world
Hey there! I'm happy to help!
Sum means you add. Let's call our number n.
n+15
We double the whole thing.
2(n+15)
This is equal to something.
2(n+15)=
Difference means you subtract.
2(n+15)=n-6.
Have a wonderful day! :D
We can use Copy Dot Flip to solve.
~Copy
3/4 ÷ 3/8
~Dot
3/4 · 3/8
~Flip
3/4 · 8/3
~Multiply both numerators and denominators.
3*8/4*3
~Simplify
24/12
~Simplify
2
The quotient is 2
Best of Luck!
