(8n^2+6n+7)-(3n+2)

We will subtract the like terms as 6n and 3n, 7 and 2

Remember (-)(+) = (-) and (-)(-) = (+)

8n^2+(6n-3n)+(7-2)=8n^2+3n+5

The answer is

8n^2+3n+5

PLEASE HELP ME I WILL MARK CORRECT ANSWER BRAINLIEST
Assoli18 [71]

Answer:

36 units

Step-by-step explanation:

to do this you must first find the lengths of all the sides with pythagorean theorem

for a to b you use

3^2 + 4^2 = c^2

9 + 16 = c^2

25 = c^2

c = 5

5 is one of the lengths

b to c uses the same equation

so

5 is another one of the lengths

for d to c your equation is

5^2 + 12^2 = c^2

25 + 144 = c^2

169 = c^2

13 is another of the lengths

d to a has the same length as c to d so there is another 13 unit length

so

5 + 5 + 13 + 13 is your equation to find the perimeter

5 + 5 + 13 + 13 = 36

that is your answer

Last months cable bill was $60, while this months is $90. This was a difference (increase) of what percent?
Ivanshal [37]

Answer:

50 % increase

Step-by-step explanation:

To find the percent increase, we take the new price and subtract the original price.  Divide it by the original price

percent increase = (new - original)/ original * 100%

                             = (90-60)/60 * 100%

                              = 30/60 *100%

                               =.5 *100%

                               =50%
