Answer:
A, E
Step-by-step explanation:
We can use rules of fractions and negatives to determine that B, C, and D are incorrect and A and E are correct.
Let s represent the short side of the triangle. The long sides of the triangle are each s+1, and the triangle's perimeter is
... s + (s+1) + (s+1) = 3s+2
The length of one side of the square is s-2, and its perimeter is 4 times that, 4(s-2) = 4s-8. The square and triangle have the same perimeter, so
... 3s+2 = 4s-8
... 10 = s . . . . . . . . add 8-3s to both sides
The length of the shorter side of the triange is 10 units.

Step-by-step explanation:
Answer:
0
Step-by-step explanation:
The remainder theorem says when you are dividing P(x) by (x-c), then the remainder is P(c).
So we need to evaluate x^2+2x-15 for x=3.
3^2+2(3)-15
9+6-15
15-15
0
So the remainder is 0.
