Answer:
The answer is B
Step-by-step explanation:
Given that Betty saves $161 per month which is $141 less than Jack per month. find the amount that Jack will save in 2 years.
First, find how much Jack saves. We can do this buy adding 141 to 161 since Betty saves 141 less meaning we can reverse it by adding it.
141 + 161 = 302
Now, that we know how much Jack saves per month.
Then, we have to find out how many months are in 2 years.
We already know that there is 12 months in a year, so for 2 years, we can simply multiply by 2.
12 x 2 = 24
Therefore, there are 24 months in two years.
Lastly, multiply 24 months by the amount that Jack saves to get the amount in total.
24 x 302 = 7,248
Thus, Jack will save approximately $7,248 in 2 years.
Question:- Find
Answer:- we know that
so by putting the value:-
Area of triangle=1/2(base×height)
360=1/2((4x-2)(7x+5))
720=(4x-2)(7x+5)
FOIL the binomial
720=28x^2+6x-10
Bring 720 to the other side
28x^2+6x-10-720=0
28x^2+6x-730=0
Factor 2 out
2(14x^2+3x-365)=0
Factor 2(14x+73)(x-5)=0
x-5=0
x=5
It can't be 14x-73=0 because the length can't be negative.
You're welcome.
