The simplified form of the given equation ( 2x + y = 8 ) is x = 4 - y/2.
<h3>Simplify all fractions?</h3>
Give the equation;
2x + y = 8
Subtract -y from both sides
2x + y - y = 8 - y
2x = 8 - y
Divide both sides by 2
2x/2 = ( 8 - y )/2
x = 8/2 - y/2
x = 4 - y/2
Therefore, the simplified form of the given equation ( 2x + y = 8 ) is x = 4 - y/2.

Triangle area = 8 x 3/2
= 12
12 x 2 = 24cm^2 for 2 triangles
Height of rectangle must be found, so use pythag on triangle
a^2+ b^2 = c^2
16 + 9 =c^2
C=5
A= 5 x 12
= 60
60 x 3 triangles in total is 180cm^2
180cm^2 + 24cm^2 = 204cm^2
Ans: 204cm^2
First let’s convert the mixed numbers to improper fractions 2 1/4 =9/4
Then u get 4(X-9/4) =-3.7
Now your gonna divide both sides by four
4(X-9/4) over 4 = -3.7 over 4
4/4 =1 …X=-9/4
-3.7/4 = -0.925
Now you’re going to add 9/4 to each side
X-9/4+9/4=-0.925 +9/4
-9/4 + 9/4 =0 (X)
Now you have just -0.925 and nine fourths
I converted 9/4 —> 2.25
Then u still have -0.925
So add 2.25+-0.925 u get ur X which is 1.325 (this is ur answer)
Answer:
x = 4, x = - 8
Step-by-step explanation:
(x+ 2)² = 36
√(x+2)² = + √36 √(x+2)² = -√36
x+2 = 6 x+2 = -6
x= 4 x = - 8
