Answer:
(X+4)(x+4)
Step-by-step explanation:
First find two numbers that multiply to 16 but add up to 8. That is 4 times 4. Then find the root of x squared which is x. The insert x + 4 in parenthesis for both sets because they are both positive. The two sets of parenthesis are supposed to be multiplied with the FOIL method to get x^2+8x+16. Hope this helps :)
Answer:
19
Step-by-step explanation:
just 19
1. B
∠1 and ∠3 are corresponding angles where a transversal (line r) cuts two parallel lines (p and q).
2. C
Each of the segments of ABC is twice the length of the corresponding segment of EDF. Hence the perimeter of ABC is twice that of EDF.
2+2-2*2/2 divide 2/2=
2+2-2*1 multiply 2*1=
2+2-2 add 2+2=
4-2 subtract 4-2=
2
answer= 2
Your answer would be option 2. Use the slope formula to see if any sides are perpendicular. This is because a right triangle must have 2 perpendicular sides that form a 90° angle for it to be a right triangle, so finding these would prove it.
I hope this helps!
