Answer:

-5

Step-by-step explanation:

\frac{7-2^{2}+17}{-14+(2)(5)}

Multiply 2 · 2 = 4

\frac{7-4+17}{-14+(2)(5)}

Subtract 4 - 7 = 3

\frac{3+17}{-14+(2)(5)}

Add 3 + 17 = 20

\frac{20}{-14+(2)(5)}

Multiply 2 · 5 = 10

\frac{20}{-14+10}

Add -14 + 10 = -4

\frac{20}{-4}

Divide 20 ÷ 4 = -5

-5

Answer:

-5

Step-by-step explanation:

\frac{(7-2x^{2} )+17}{-14+2*5}

Find 2 to the power of 2 which is 4

\frac{7-4+17}{-14+2*5}

Subtract 4 from 7 to get 3

\frac{3+17}{-14+2*5}

Add 3 and 17 to get 20

\frac{20}{-14+2*5}

Multiply 2 and 5 to get 10

\frac{20}{-14+10}

Add -14 and 10 to get -4

\frac{20}{-4}

Divide 20 by -4 to get -5

Sooo the answer is -5

hope this helps :)

A = 100(1+r)^4<br> Expand the right of this formula.<br> appreciate your help with an explanation
suter [353]

Answer:

100r^4 + 400r^3 + 600r^2 + 400r + 100

Step-by-step explanation:

Expanding ( r + 1 )^4 gives :-

r^4 + 4r^3 + 6r^2 + 4r + 1

So multiplying 100 with r^4 + 4r^3 + 6r^2 + 4r + 1 gives :-

100r^4 + 400r^3 + 600r^2 + 400r + 100

The Perimeter of a rectangle is 36. If there's 5n + 3 and 1/4n + 2, what's the value of n?
seropon [69]
Perimeter: 36

5n + 3 = 36
5 · 6.6 + 3 = 36

N = 6.6
------------------------------------------
Perimeter: 36

1/4n + 2 = 36
1/4 · 136 + 2 = 36

N = 136

Hopefully i understood the question correctly :) Hope this helps

Draw the graph of the equation<br><br> x+y=5
Advocard [28]

well first you have to get x and y on separate sides so subtract x by both sides to put x on the right side.

now you have y = 5 - x

to graph that let's throw in some numbers for x and y and make a function table

x, y

1, 4

2, 3

3, 2

4, 1

5, 0

6, -1

and so forth

as you can see as x increases in value, y decreases in value

all you have to do now is plot those points on a graph

BRAINLIEST AND 30 POINTS!!! HURRY!!
Gekata [30.6K]

Answer:

C. 72

Step-by-step explanation:

the answer is C because if you divide 84 by 7 you get 12 so you then multiply 6 by 12 and get 72. the answer could not be negative 72 because that would then make the equation positive.
