To factor: Notice that when you factor it should turn out to be a binomial x binomial.
x^2-10x+25
When factoring you can look at the operation at the end right before the last digit. If the operation is positive then you will use the first operation in the binomial for factored number. For example the ending operation is positive and the first operation is subtraction so both binomial will be subtraction.
I know it would be factored (x-5)(x-5) and I can prove it by multiplying it out.
x^2 -5x-5x+25
x^2-10x+25
Hey don’t worry about that grade just keep practicing maths and honestly at one point you’ll start understanding the concepts trust me. Just do it a lot.
So here are my explanations
Answer:
Surface area means all of the outside areas, kind of like when you wrap a present.
Step-by-step explanation:
1st draw the box and find the area of the top and the bottom of the figure
10 x 3 = 30 for the top and 30 for the bottom, so 60 for both.
2nd find the area of two opposite sides:
10x 4.5 = 45 for one side and 45 for the other side, which is 90 for both
3rd find the area of the last two opposite sides:
3 x 4.5 = 13.5 for one side and 13.5 for the other side, so 27 for both.
4th: now add all those sides 60 + 90 + 27 = 177 inches squared.
Answer:
(-2,-3), (0,-3), (-1,1)
Step-by-step explanation:
When reflecting over an axis, the axis you are reflecting over stays the same while the opposite axis becomes its opposite number, like reflect (12, -9) over the y axis, the y (-9) would stay the same but the x (12) would become (-12)
Answer:
39.5
Step-by-step explanation:
angle ABC=60=(5x+2)+(3x-2)
60=8x
x=7.5
Angle ABD=(5x+2),(sub x=7.5)
=(5*7.5+2)
=39.5
