Answer:
missing coffecient is 8
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
y-(a*(x-3)*(x+5))=0
STEP
1
:
Equation at the end of step 1
y - (a • (x - 3) • (x + 5)) = 0
STEP
2
:
Equation at the end of step 2
y - a • (x - 3) • (x + 5) = 0
STEP
3
:
Equation at the end of step 3
y - ax2 - 2ax + 15a = 0
STEP
4
:
Solving a Single Variable Equation:
4.1 Solve y-ax2-2ax+15a = 0
In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

Answer:
Volume = 11680.44 cubic inches
Step-by-step explanation:
Circumference of the trunk of a tree = 2πr
Here, r = radius of the trunk
26π = 2πr
r = 13 inch
Since, volume of the cylindrical trunk = πr²h
= π(13)²(22)
= 3718π
= 11680.44 cubic inches

Answer: rounded to the tens is 10 the tens place is the one in 12.81 or like the one in 13.81
Step-by-step explanation:
The answer is plus 4 because a positive plus a negative is a negative
Multiply 80 by 14 to get how many total people they can feed.
80 times 14 is 1120.
Now, divide 1120 by 32 to get how many days the food will last if 32 people come every day.
1120/32 = 35.
The answer is B, 35 days
