7 / 7 = 1
3 + 1 = 4
4 + 3 and 1 / 3 = 7 and 1 / 3
Answer:
A. The lines stay parallel
Step-by-step explanation:
Rigid transformations do not change angle or line relationships. When the parallel lines are rotated they stay parallel. Reflecting them will keep them parallel. If this were not true, then figured with parallel lines like rectangles and squares would change shape when reflected.
a perfect square trinomial has a factor that is identical to the other factor. In this case, from the first term, the factor is composed of 2x while from the third term, there is a term 7 involved. In this case, the factor is 2x + 7. so the second term has to be 2*(2*7) equal to 28
Answer:
HELPP
Step-by-step explanation:
LOl
X^2+2x-63
(x+9)(x-7)
since x is squared, you immediately know that it multiples itself. (x)(x) is x^2. I used the FOIL method where you do first, outside, inside, last. so the first amount in each parentheses is a x and a x. that equals x^2. then the outside numbers are 7 and a x. That equals-7x. on the inside, I have +9 and x. that is +9x. Lastly, a -9 and -7 is -63. When written out in a number sentence, and combine like terms, you will get your original answer so (x+9)(x-7) is the factored form
