A) $355 + $18x = $514 + $15x

B) $355 + $18x = $514 + $15x
355 -355 + 18x = 514 -355 + 15x
18x = 159 + 15x
18x-15x=159+15x-15x
3x = 159
3x/3=159/3
x = 53

C) $355 + $18(53) = $1309
$514 + $15(53)= $1309

D) You can check your answer by taking what x equals and plugging back into the original formula of $355+$18x=$514+$15x. Then solve making sure the left side equals the right side.

$355+$18x=$514+$15x
$355 + $18(53)=$514 + $15(53)
$1309 = $1309

R^2+8r=-7<br>solve the equation with the quadratic formula showing work

Yuliya22 [10]

Answer:

Step-by-step explanation:

r²+8r=−7

Step 1: Subtract -7 from both sides.

r²+8r−(−7)=−7−(−7)

r²+8r+7=0

Step 2: Use quadratic formula with a=1, b=8, c=7.

r= $r=\frac{-b+or-\sqrt{-4ac} }{2a}$

$r=\frac{-8+or-\sqrt{(8})^2-4(1)(7) }{2(1)}$

A= 3
b= 4

=3.14(a^2 + ab)
substitute the given a & b values in expression

=3.14((3)^2 + (3*4))
multiply inside parentheses

=3.14(9 + 12)
add inside parentheses

=3.14(21)
multiply

=65.94
