Answer:
Step-by-step explanation:
x + 0.7 = 1 - 0.2x
Add 0.2x to both sides
x + 0.2x + 0.7 = 1 - 0.2x + 0.2x
1.2x + 0.7 = 1
Subtract 0.7 from both sides:
1.2x + 0.7 - 0.7 = 1 - 0.7
1.2x = 0.3
Divide both sides by 1.2:
1.2x/1.2 = 0.3/1.2
x = 0.25
Answer:
14 cm
Step-by-step explanation:
One side of the composite has a length of 6 and the other side has a length of 8.
If we add these two numbers, we'll get the missing side length of the rectangle
6 + 8 = 14 cm

Answer: The side length of the pet shop sign=5/4 inches
Step-by-step explanation:
Given: Candy draws a square design with a side length of x inches for the window at the pet shop.
She takes the design to the printer and asks for a sign that has an area of
square inches.
Let y(x) =
differentiating both sides w.r.t x we get
y'(x)=32x-40
to find critical point x ,Put y'(x)=0 then
⇒32x-40=0
⇒x=5/4
Therefore the side length of the pet shop sign=5/4 inches.
