Answer:
kites have 2 pairs of congruent sides and kites have 2 pairs of consecuitive side
Step-by-step explanation:
By concepts of polynomials and systems of linear equations, the constants c and d of the expression p(x) = x⁴ - 5 · x³ - 7 · x² + c · x + d are 29 and 30.
<h3>How to determine the missing coefficients of a quartic equation</h3>
A value x is a root of a polynomial if and only if p(x) = 0. We must replace the given equation with the given roots and solve the resulting system of <em>linear</em> equations:
(- 1)⁴ - 5 · (- 1)³ - 7 · (- 1)² + (- 1) · c + d = 0
- c + d = 1 (1)
3⁴ - 5 · 3³ - 7 · 3² + 3 · c + d = 0
3 · c + d = 117 (2)
The solution of this system is c = 29 and d = 30.

Answer: for first one x=28-5y
second one x=-3/29(y-7)
Step-by-step explanation:
im sure its right
The answer is D. Most of the other answers are way to high to make sense
Change 5/8 and 3/10 so they have the same denominator
5/8×5/5=25/40
3/10×4/4=12/40
25/40+12/40=37/40
5/8+3/10=37/40
