Given
base=2x+6
height=x+4
and
area=56 square units
56=1/2 times (2x+6) times (x+4)
times bot sides by 2
112=(2x+6)(x+4)
expand
112=2x²+14x+24
divide both sides by 2
56=x²+7x+12
minus 56 both sides
0=x²+7x-44
factor
waht 2 numbers mulitply to get -44 and add to get 7
11 and -4
0=(x-4)(x+11)
set to 0
x-4=0
x=4
x+11=0
x=-11
false, measures can't be negative
x=4
height=x+4
height=4+4=8
base=2x+6
base=2(4)+6=8+6=14
x=4 and base=14 and height=8
If it’s asking if it’s true of false it’s false
Because 5/11x6/7 =30/77

<h2>
Answer:</h2>
x = 1
y = 1
<h3>
Step-by-step explanation:</h3>
Substitute into one of the equations
Rearrange variables to the left sider of the equation
Combine like terms
Divide both sides of the equation by the coefficient of variable
Determine the sign for multiplication or division
Cross out the common factor
Substitute into one of the equations
The solution of the system is
