The area is 24 square inches. So its dimensions in inches
must be factor-pairs of 24 .
Those are
1 x 24
2 x 12
3 x 8
or
4 x 6 .
Answer:
36
Step-by-step explanation:
f(x)=x^2+2x+1
Let x = -7
f(-7)=(-7)^2+2*-7+1
= 49-14+1
= 36
If u multiply the first equation by -4, u get -2x - y = -20
and when u add the 2 equations..
-2x - y = -20
2x + 3/8y = 5
-----------------
0 - 5/8y = -15.....u notice that the x terms r eliminated.

Answer:
Step-by-step explanation:
Set up two equations with the information given-- and things you know from experience: a penny is worth 1 cent and a nickel is worth 5 cents. $ 2.38 is 238 cents (so you can eliminate decimals for now)
Put those values into an equation about the total value:
p + 5n = 238
and you know the total number of coins is 66.
p + n = 66
get a value for p by "solving" (subtract n from both sides)
p = 66-n
Substitute that value for p in the first equation. Then solve.
(66 -n) + 5n = 238
4n = 238-66 Then isolate n by dividing both sides by 4
n = 172/4
n = 43 Substitute that in the second equation, then solve for p
p + 43 = 66 p = 66 - 43
p = 23
So Chuck has 23 pennies and 43 nickels
