Answer:

hope it helps!

Step-by-step explanation:

Perimeter includes three sides of rectangle:

15m + 12m + 15m

Plus half of circle with diameter 12m

Circumference = diameter * PI

Circumference = 37.68m.

1/2 circumference = 18.84m

Total perimeter is 15m+12m+15m+18.84m

60.84m

Answer:

C. 125 + 120x = 180 + 110x

t = $5.5

Step-by-step explanation:

A.125t + 120 = 180t + 110

B. 120t + 110t = 125 + 180

C. 125 + 120t = 180 + 110t

D. 125 - 120t = 180 - 110t

Friday

$125 + 120t

Saturday

110t + 180

equate Friday and Saturday

125 + 120t = 110t + 180

Collect like terms

125 - 180 = 110t - 120t

-55 = -10t

Divide both sides by -10

t = -55 / -10

= 5.5

t = $5.5

Solve for x -<br><br><img src="https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20%2B%205x%20%2B%206%20%3D%200%20%5C%5C%20%5C%5C%20" id="T

Hello,

x² + 5x + 6 = 0

a = 1 ; b = 5 ; c = 6

∆ = b² - 4ac = 5² - 4 × 1 × 6 = 25 - 24 = 1 > 0

2 solutions :

x_{1} =  \frac{ - b -  \sqrt{\Delta} }{2a}  =  \frac{ - 5 - 1}{2 \times 1}  =  \frac{ - 6}{2}  =  - 3

x_{2} =  \frac{ - b  +   \sqrt{\Delta} }{2a}  =  \frac{ - 5  + 1}{2 \times 1}  =  \frac{ - 4}{2}  =  - 2

S = { -3 ; -2}
