Answer:
x = 56/3
PS = 103/3
Step-by-step explanation:
Perimeter: (4x + 1) + 2(2x - 3) + (4 + 4 + 4x + 1) = 228
Collect and combine like terms: 12x + 4 = 228
Subtract 4 from both sides: 12x = 224
Divide both sides by 12: x = 56/3
PS = (2 x 56/3) - 3 = 103/3
Answer:
Step-by-step explanation:
<u>Cost of each item:</u>
- Pizza = $1.50, Hotdogs = $1.25
<u>Number of each item:</u>
- Pizza = x, Hotdogs = x + 20
<u>Total cost:</u>
- 1.25x + 1.5(x + 20) = 173
- 1.25x + 1.5x + 30 = 173
- 2.75x = 143
- x = 143/2.75
- x = 52
<u>Number of slices of pizza:</u>
Answer:
9x^2+4x+5
Step-by-step explanation:
f ( x ) = 5x^2 - 2x + 6
g ( x ) = 4x^2 + 6x - 1,
Add the functions together
f(x)+ g(x) = 5x^2 - 2x + 6 + 4x^2 + 6x - 1
Combine like terms
=9x^2+4x+5
Answer:
55.000000000001
Step-by-step explanation:
I hope this helps you
x^2+x-6 = (x+3)(x-2)
x => +3
x => -2
x^2-2x-15= (x-5)(x+3)
x => -5
x => +3
(x+3)(x-2)/(x-5)(x+3)
x-2/x-5
