4² = 16Step-by-step explanation:
x² + 8x = 6x² +2*x*4 + 4² = 6 + 4²(x + 4)² = 22Number needed is 4² = 16
Answer:
Solution given:
x² + 8x =6
x²+2.x.4+4²-4²=6
(x+4)²=6+16

no needed is 4² or 16.
A coat at a store is originally priced at $54.99. The store marks the price down to $32.99. To the nearest percent, what is the percent markdown of the coat?
Answer:

the percent decrease
Step two:
the percent decrease= change in price/ old price*100

This is solving quadratic functions by square roots
Answer:
x = 13 and x = -3
Step-by-step explanation:
divide each side by 2 first and get:
(x-5)² = 64
take the square root of each side next and get:
x - 5 = [tex]\sqrt{64}[/tex]
x - 5 = 8 and x - 5 = -8
x = 13 and x = -3
Answer:
x = 13 and x = -13

The circumference of each of the smaller circles is 12 mm. Find the area of the shaded region.
Answer:
11.45mm^2
Step-by-step explanation:
Given data
Circumference= 12mm
The expression for the circumference is
C= 2πr
12= 2*3.14*r
12= 6.28r
r= 12/6.28
r= 1.91mm
Hence the area of each small circle is
A= πr^2
A= 3.14*1.91^2
A= 3.14*3.6481
A=11.45mm^2

Help me pls ( only correct answers) tyy
Answer:
100 cubic in
Explanation
step 1: divide the figure into two
step 2 : find area then multiply by height of the cuboid
step 3 : add both
Answer:
The answer is 100.
Step-by-step explanation:
Volume = weight times height times length = 5 times 1 times 8 = 40
Volume = weight times height times length = 5 times 2 times 6 = 60
So now that we have the volume of each rectangular prism, we must add them together to get the full volume.
60 + 40 = 100
what is 3053.62805928 to the nearest cubic inch
Answer:
3054
Step-by-step explanation:
When you round to the nearest unit, in this case inch, you need to look at the tenths place.
5 or more raise the score
4 or less, let it rest.
------------------------------------------
Since the number in the tenths place is a 6, it will bump up the number to a 3054.
Good Luck!

The grades for 200 students at a middle school are represented in the graph below how many more students earned Cs then Ds
Answer:
B. 60
Step-by-step explanation:
There are a total of 200 students here, and 45% got Cs, to find how many got Cs, multiply 200 by 45%, or 0.45: 200*0.45 = 90, 90 people got Cs.
15% got Ds, multiply 200 by 15%, or 0.15 to get 30, 30 got Ds
The amount who got Cs minus the amount who got Cs is 90 - 30 = 60, 60 more students got Cs than Ds

You rent an apartment that costs $1700 per month during the first year, but the rent
is set to go up 9% per year. What would be the rent of the apartment during the 12th
year of living in the apartment? Round to the nearest tenth (if necessary).
Answer:
$4386.70Step-by-step explanation:
The rent will increase 11 times before the 12th year
Required equation:
$1700*(1 + 0.09)^11 = $4386.70 (rounded)its a function or not fuction?
answer:
it's a function
step-by-step explanation:
according to g00gle- in mathematics, a function is a binary relation between two sets that associates to each element of the first set exactly one element of the second set. typical examples are functions from integers to integers, or from real numbers to real numbers.
but the simple definition is that a function is when the x value isn't being repeated. and since in your case it isn't, the table is a function
another way to solve-
for this, we will put the pairs into a graph then perform the line test-
as you can see each point has its own individual line, therefore, meaning it passed the vertical line test
good luck :)
i hope this helps
brainliest would be highly appreciated

According to historical data, it is believed that 12% of American adults work more than one job. To investigate if this claim is still accurate, a random sample of 100 American adults is selected. It is discovered that 18 of them work more than one job. A researcher would like to know if the data provide convincing evidence that the true proportion of American adults who work more than one job differs from 12%. What are the values of the test statistic and P-value for this test?
