Answer:
Step 4
part a: no answer yet still having trouble showing my work
part b:
-0.125(x-24)^2+50
-0.125(x-24)(x-24)+50
-0.125(x^2-24x-24x+576)+50
-0.125(x^2-48x+576)+50
-0.125x^2+6x-75+50
-0.125x^2+6x-22
a=-0.125
b=6
c=-22
part c: yes he went through
part d:
plug in roots (4,0) and (44,0)
if x is 4 and y is 0
0=-0.125(4)^2+6(4)-22
0=-2+24-22
0=-2+2
0=0
if x=44 and y=0
0=-0.125(44)^2+6(44)-22
0=-242+264-22
0=-242+242
0=0
Answer:
Step-by-step explanation:
price of 1 pen= $ 2
price of 1 pencil= $1
total money spent= $12
Let the number of pen be a and number of pencil be b.
2 a + b = 12 ----------------Equation 1
We have, she bought 3 more pens than pencils
a - b = 3 ------------------ Equation 2
Equation 1 +Equation 2,
2 a + b + a - b = 12 + 3
3a = 15
a = 5
Substituting in equation
5 - b = 3
b = 2
Number pencils Ava bought = 2
The word "difference" means "subtract" so B. Wouldn't be B. Because it's adding. This leaves us with A,C, and D
For A. It's a positive one (so this can't be your answer)
For D the negative one is in the front
The question isn't asking the different -1 and -12
So, this leaves us with option C as your answer
Good luck on your assignment and enjoy your day!

Answer:
144.75in^2
Step-by-step explanation:
V=bh/3
so..
V=(18.4)(23.6)/3
V=434.24/3
V=144.74666
round to the nearest tent
V=144.75 inches
