Answer:
20 inches x 26 inches
Step-by-step explanation:
set up an equation: (2x)(x+7)=520
now just solve it
2x^2+14x=520
x^2+7x-260 = 0
factor: (x-13)(x+20)
x = 13 and -20
13 is the only one that works because you can't have a negative side length
13+7=20
13*2=26
lmk if you don't understand how to solve that equation
Answer:
240 minutes or 4 hours
Step-by-step explanation:
So if it takes Erica 80 minutes to analyze the company's monthly credit card statements, she will get 30/80 of it done in 30 minutes.
If it takes Alexa 2 hours to analyze the company's monthly credit card statements, she will get 30/120 of it done in 30 minutes.
Add 15 to each of the fractions because they analyze the company's monthly credit card statements with Mack for 15 more minutes.
So you have 45/80 and 45/120.
Now add both fractions by finding the lowest common denominator which is 240.
135/240 + 90/240 = 225/240
So Mack did the remaining 15/240.
Now to find how long it would take him to analyze the company's monthly credit card statements by himself divide 240 by 15 which is 16.
Then multiply
15 x 16 = 240
so it would take him 240 minutes or 2 hours.
Answer:
We show that f(x) n+8/6n = 6 x n = 0
which flips the n+8/1 = 0+8/0-6= x = 3 this is the range.
For the HA we would work left to right.
x goes to positive or negative infinity and is determined by the highest degree terms of the polynomials in the numerator and the denominator. This particular function has polynomials of degree 0 in both the numerator and the denominator
If say n+8 was n+2 then we would use the 2/-2+3 and get 1 and show the hole as the source;
hole : -2+1 as non equal sign. but not in the case of n+8/6n
-2+1 represents 1/3 symmetry.
We see for n+8/6n with interpreted back into the zero format minus
-0+8/-0-6 we see there is symmetry and can work on the left side of graph and flip over. Where 0 = n+8 and 1=nx6
Step-by-step explanation:
There would be no way of doing the others unless the exponents had been squared ^2
If they were squared then the domain will be (-infinity -3) parenthesis
union of( -3 -2) union of +2 to negative infinity.
There is not a vertical asymptote as the numerator divides into dominator at point 8 as a decimal.
The holes are then closed.
Answer: 56
Step-by-step explanation: 7*480= 3360
3360/60= 56
