X-1=5x+3x-8help this confused child

1 answer:

4 0

X-1= 5x+3x-8

Combine like terms
x-1= 8x-8

Our goal is to isolate x by cancelling out other numbers.
Subtract x from both sides
x-1-x= 8x-x-8
-1= 7x-8

Add 8 to both sides
7=7x

Divide both sides by 7
1=x

Final answer: x=1

Answer:

137.5 in^2

Step-by-step explanation:

So, this is basically a rectangle and two right-sides triangles.

First the rectangle: Formula is A=wl

Replace the Values: A = 14*7 98 in^2

Then we solve for the two right-sides triangles.

A= 1 /2a h= 1 /4 b ^2 sin (2 θ )

Top trinangle= A = 25.5 in^2 (height 7 in base 7 in)

Bottom Trinagle A = 14 in^2 (height 7 in base 4 in)

Add results:

98+25.5+14 = 137.5 in^2
