Answer:
A
Step-by-step explanation:
Treat it like algerba
finding C
what subtracted from $4,000 gives $ 350
$3,650
The equation for the perimeter of a square is P=4s (s=the length of each side)
So we can plug in the perimeter and solve for the side
48=4s
s=12 (divide both sides by 4)
The equation for the area of a square is A=s^2 or A=s*s
We can plug in the value for each side to find the area
A=12*12
A=144 units
Hope this helps!
The first is C. The second is A.
Answer:
-2.1x +14.4y
Step-by-step explanation:
Use the distributive property to eliminate parentheses. Then combine like terms.
(12.7y-3.1x)+5.9y-(4.2y-x)
= 12.7y -3.1x +5.9y -4.2y +x
= x(-3.1 +1) +y(12.7 +5.9 -4.2)
= -2.1x +14.4y
Answer:
Step-by-step explanation:
lm=6x+3
mn=4x-17
ln=x+14
lm+mn>ln
6x+3+4x-17>x+14
10x-14>x+14
9x>28
x>28/9
mn+ln>lm
4x-17+x+14>6x+3
5x-3>6x+3
-x>6
x<-6
lm+ln>mn
6x+3+x+14>4x-17
7x+17>4x-17
3x>-34
x>-34/3
combining x<-6 or x>28/9
