Answer:
D)210 units ^2 I hope the answer is correct. I will be happy when I get 10 points
X² + 20x + 100 = 36⇒ x² + 20x + 100 - 36 = 0⇒ x² + 20x + 64 =0
Δ = b²-4ac = 20² -4·1·64 = 400-256 = 144
x₁= (-b+√Δ)/2a = (-20+√144)/2·1 = (-20+12)/2 = -8/2 = -4
x₂= (<span>-b-√Δ)/2a = (-20-√144)/2·1 = (-20-12)/2 = -32/2 = -16
x=-4 or x=-16</span>
Answer:
x = 2
y = 3
Step-by-step explanation:
add the 2 together and the y-values drop out and you are left with:
8x = 16
x = 2
3(2) + 2y = 12
2y = 6
y = 3
Answer:
C
Step-by-step explanation:
12 decreased by 2 times x
