Answer:
Step-by-step explanation:
The equation to solve is:
To get rid of the "square", we need to take square root of both sides:
Then we use algebra to find the value(s) of x. Remember, when we take square root, we have to add up a "+-" (on the right side). Shown below:
So these are 2 answers for x.
Answer: b) x = 6 and total line is 52
c) x = 5.5 and total line is 20
Step-by-step explanation:
b) (x+20) = (5x-4)
4x = 24
x = 6
Line (x+20) = 26
Line (5x-4) = 26
Total line = 52
c) (4x-12) = (-2x+21)
6x = 33
x = 5.5
Line (4x+12) = 10.0
Line (-2x+21) = 10.0
Total line = 20
Answer:
-3/5
Step-by-step explanation:
Parallel lines have the same slope. If ab has a slope of -3/5 and is parallel to cd, the cd has a slope of -3/5

Follow the reasoning.
288 ÷ 2 = 144
and 144 its a perfect square (144 = 12²)
It is visible that if we multiply 288 by 1/2, we will obtain a perfect square, but we will do this via a simple equation
288 · X = 144
X = 144 ÷ 288
X = 0,5 ⇔ X = 1/2
