Answer:
x(7 - x)
Step-by-step explanation:
Given
7x - x² ← factor out x from both terms
= x(7 - x) ← in factored form
Answer:
a
Step-by-step explanation:
Quotient rule says we can divide 192 and 3 because they are both under the radical. This gives us the square root of 64.
We can also divide x^3 and x to get x^2.
The square root of 64x^2 is 8x
Answer:
All angles in a triangle sum up to 180 degrees.
So, 63+71+x=180 degrees.
You add like terms: 134, and then add x.
134+x=180 degrees.
Minus x from both sides.
180-134=x.
What do you think x is?
