Answer:
40. D. 5x-14
Step-by-step explanation:
Take the GCF (-8t) of the given expression.
You'll get -8t(2t-5).
Now, set each equal to zero and solve for x.
-8t = 0 2t-5=0
t=0 t = 5/2 (Or 2.5 seconds)
<B+<D = 180
x+148 = 180
x = 32
<A = 2(32) + 1
<A = 64+1
<A = 65
Answer:
the 15 year olds do
Step-by-step explanation:
X = 12
Use the Pythagorean Theorem.
13^2 = 5^2 + x^2
169 = 25 + x^2
Subtract 25 from both sides.
144 = x^2
Take the square root.
12 = x
