(
) ≈ 12.84° → D
Answer:
x=-1
y=-3
Step-by-step explanation:
3x-2y=3(1)
5.(1) <=> 15x-10y=15 (2)
15x-4y=-3 (3)
(2)-(3) <=> -6y=18
Answer:
a = 
Step-by-step explanation:
Given
ga + q = r ( subtract q from both sides )
ga = r - q ( isolate a by dividing both sides by g )
a = 
Ok
Perimeter=38cm
Area=88cm
2 numbers that multiply to 88
4 numbers that add up to 38
Length=11
Width= 8
