answer:
x^2 - 2 x + 4
explanation: you want to factor the expression using a^3 + b^3= (a+b) (a^2 - ab+b^2)
then
(x,2) x (x^2 - 2x+4)
_________________
x+2
then reduce so,
(x+2) x (x^2- 2x +4)
_________________
x+2
then cross out repeating which is x+2
then you get your answer!

A utility pole is 24 feet tall and its shadow is 45 feet long. A nearby water tower is 32 feet tall. How long is the water tower's shadow?
Answer: The tower's shadow is 60 feet long.
Step-by-step explanation:
We can use a ratio to solve this:
24/45 = 32/x
Cross multiply: (Numerator of left side times the denominator of right side, and denominator of the left side by numerator of right side.)
24x = 32(45)
24x = 1440 divide both sides by 24
x = 60
ill give a brainest no cap plz actually help
Step-by-step explanation:
Amount borrowed=400
interest rate=4%
Amount of interest after x years =0.04XxX400=$16x
Total to be paid back=400+0.04XxX400=400+16(1)
1) the amount of interest.if Franco pays back the loan in x=1 years is
16x1=$16
2) the amount of interest,if Franco pay back the loan in x=2 years is,
16x2=$32
3) the amount of franco will pay the lender after 2 years will be
400+(16x2)=400+32=$432
Stephanie put $80 in her bank account when she was 5
years old. The bank gave her a simple interest rate of 2.1%.
Does she have enough money to buy a TV for $1,000 after
leaving her money in the bank for ten years?
Answer:
Mynd44
Step-by-step explanation:
Here, we want to check if the amount of money saved is enough to
by a tv
Mathematically, we have the simple interest formula as follows;
I = PRT/100
I = (80 * 2.1*10)/100
I = 1680/1000 = 1.68
Hence, she will not have enough

-16/5, 8, -20. What is the next term of the geometric sequence.
The nth term of a geometric sequence is expressed as:
Tn = ar^n-1
From the sequence:
a is the first term = -16/5
n is the number of term = 4(since next term is 4th term
r is the common ratio = (8)÷(-16/5) = 8×-5/16
r = -5/2
Substitute the given values into the formula
T4 = -16/5(-5/2)^4-1
T4 = -16/5(-5/2)³
T4 = -16/5×-125/8
T4 = -16/8×-125/5
T4 = -2×-25
T4 = 50
Hence the next term is 50

-7(x+5) =21
apply the distributive property and simplify
Answer:
x=−8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−7(x+5)=21
(−7)(x)+(−7)(5)=21(Distribute)
−7x+−35=21
−7x−35=21
Step 2: Add 35 to both sides.
−7x−35+35=21+35
−7x=56
Step 3: Divide both sides by -7.
−7x/−7 = 56/−7
x=−8
Answer:-
Distributed: -7x+(-35)=21 Simplified: x=-8
Step-by-step explanation:-
Distributed:
-7(x+5)=21
(x*(-7))+(5*(-7))=21
-7x+(-35)=21
Simplified:
-7x-35=21
-7x=21+35
-7x=56
x=-8

Written as a simplified polynomial in standard form, what is the result when ( x + 2 ) 2 (x+2) 2 is subtracted from 7 x − 4 7x−4?
Answer:
-x²+3x-8
Step-by-step explanation:
Given polynomials are :
f(x) = (x+2)²
p(x) = 7x−4
We need to find a simplified polynomial when f(x) is subtracted from p(x) i.e.
p(x) - f(x) = 7x−4 - (x+2)²
We know that, (a+b)² = a²+b²+2ab
So,
p(x) - f(x) = 7x−4 -(x²+2²+2(x)(2))
= 7x−4 -(x²+4+4x)
= 7x−4-x²-4-4x
= -x²+3x-8
Hence, the result will be -x²+3x-8.

Jesse owns a sporting goods store that sells skis and snowboards. The store earns a profit of $52 for each ski sold and a profit of $64 for each snowboard sold. If Jesse's store sells a total of 83 pairs of skis and snowboards and earns a profit of $4892 in November, how many pairs of skis and snowboards did the store sell that month
Answer:
9
Step-by-step explanation:
I multiply 52 and 83 and get 4316. 4892 - 4316 is 576. 576 divided by 64 is 9!
Answer: they sold 35 skis and 48 snowboard
Step-by-step explanation:
52 x 35 = 1820
64 x 48 = 3072
1820 + 3072 = 4892
owen and needed to get his computer fixed he took it to the repair store the technician at the store worked on the computer for 5.5 hours and charged him $70 for parts the total is $702.50 what was the total cost of labor per hour
To figure out this problem, let's set up an equation first to make it easier:
702.50 = 5.5x + 70
x = amount charged per hour
702.50 = 5.5x + 70
-70 -70
-----------------------------
632.5 = 5.5x
/5.5 /5.5
--------------------
115 = x
Owen was charged $115 per hour
