Answer:
Factoring a perfect square trinomial.
Step-by-step explanation:
The left side was able to be simplified via factoring.
You first see where it starts on the y axis. whether it be 1 or 2 or 3 or even 3. Than you look at the slope by counting from that point from the y axis going up and over until you reach a point. not a line a point. and if it's 3 up and one over than it's 3x. But it's for example it's 3 up and 2 over than it's 3/2x. Than you set up the equation as y= mx + b. m being the slope that you found. x just remains the same. and b is where the point started on the y axis
Answer:
Root, in mathematics, a solution to an equation, usually expressed as a number or an algebraic formula.
Answer:
x-30
Step-by-step explanation:
Firstly, you do the first step, which is, 3x-18+4x+12-6x, then you continue simplifying it: 7x-18+12-6x.
Keep it on and on, the next step: x-18+12, add 18 and 12 together you get 30.
So the final answer is x-30
Answer:
Angle C = 45 degrees.
Angle D = 30 degrees.
Step-by-step explanation:
Angle C = 45 + 90 = 135 180 - 135 = 45.
Angle D = 180 - 45 = 135 (angle F) 15 + 135 = 150 180 - 150 = 30
