Answer:
Each get 5
Step-by-step explanation:
Hey there!!
Given equation :
( x - 1 ) / 4 = ( x + 2 ) / 3
First step we will need to take is to cross-multiply. In cross-multiplication, we will have t multiply the denominator with the numerator on both the sides. In this case, we will have to multiply 4 with x + 2 and 3 with x - 1.
... 4 ( x + 2 ) = 3 ( x - 1 )
... 4x + 8 = 3x - 3
Subtract 3x on both sides.
... x + 8 = -3
Subtract 8 on both sides
... x = - 11
Hope my answer helps!
For the first question you just need to add up all the sides. so first add all the x numbers and then add all the plain numbers.
a perimeter is the total length around the shape.
The formula is y=MX+b so m=3/2 b=-1
