Answer:
It has two congruent angles because if they do have two congruent angles, then they are called and isosceles triangle. Hope this helps and if it did, please mark as brainliest.
No, b/c one would be 3x + 2 while the other is 5x. plug in a few numbers and you'll see they're not the same
Answer:
y = -16 (x − 3/8)² + 49/4
Step-by-step explanation:
y = -16x² + 12x + 10
First, factor the leading coefficient from the first two terms.
y = -16 (x² − 3/4 x) + 10
Complete the square. Take half of the b coefficient, square it, then add and subtract the result.
b = -3/4
b/2 = -3/8
(b/2)² = 9/64
y = -16 (x² − 3/4 x + 9/64 − 9/64) + 10
y = -16 (x² − 3/4 x + 9/64) + 9/4 + 10
y = -16 (x − 3/8)² + 49/4
