Answer:
D, 5m+3
PLEASE MARK BRAINLIEST
Step-by-step explanation:
Distribute:
=(3)(m)+(3)(1)+2m
=3m+3+2m
Combine Like Terms:
=3m+3+2m
=(3m+2m)+(3)
=5m+3
Putting equation
0 = -16t² + 36t + 4
<span>0 = -8t² + 18t + 2 ← Complete the square to solve </span>
<span>-8(t² - 9t/2) = -2 </span>
<span>8(t² - 9t/4 + 81/64) = 2 + 81/8 </span>
<span>8(t - 9/8)² = 97/8 </span>
<span>(t - 9/8)² = 97/64 </span>
<span>t -</span><span> (t = 0) </span>
<span> (h = 0) at: </span>
<span>t = (9 + √97)/8 ≅ 2.356 seconds
hope it helps</span>
Answer:28
Step-by-step explanation:
28/2=14
14+4=18
X²>49
well, I don't know a formula but this is how I would solve it
I first solve x²=49 to obtain x=+/-7
so then would it be x>+/-7?
if we try 8 it works
if we try -9 it works
so answer is x>+/-7
basically x<-7 or x>7
