Solve the equation using substitution?
Answer:
21x^2-2x+1
Step-by-step explanation:
The area of shaded region= The area of the floor - area of the identical islands
The area of shaded region=(5x+1)^2-2*(2x)(x+3)=25x^2+1+10x-4x^2-12x=21x^2-2x+1
The easy thing to do is eliminate x by subtraction
x + 7y = 24
- x - 9y = -24
-------------------
16y = 48
now solve for y and then substitute the value into either original equation to find x
Answer:
$1,479.45
l= $50.000*0.06(6%=0.06)*(180/365)
I=3000*0.4931
I=1,479.45
Step-by-step explanation:
we know that
the speed's formula is equal to

in this problem we have

Substitute the values in the formula


therefore
<u>the answer is</u>
