Each pencil costs $0.40 because
4.00/10=.40
Answer:
A. 13
Step-by-step explanation:
Pythagorean Theorem: a^2+ b^2=c^2
a = 12
b = 5
c = ?
12^2+5^2=c^2
144 + 25 = c^2
169 = c^2
c = sqrt(169)
c = 13
Answer:

Answer:
The answer is
<h2>1225</h2>
Step-by-step explanation:
4x² + 5 - 6x³ + 3x⁴ - x
x = - 4
Substitute the value of x into the expression
That's
4(-4)² + 5 - 6(-4)³ + 3( 4 )⁴ - - 4
Simplify
4(16) + 5 - 6( -64) + 3( 256) + 4
64 + 5 + 384 + 768 + 4
We have the final answer as
<h3>1225</h3>

Answer:
-2a + 20b - 2c
Step-by-step explanation:
(6a + 5b + 4c) + (–6c + 15b) + (–8a) = 6a + 5b + 4c - 6c + 15b - 8a
= 6a - 8a + 5b + 15b + 4c - 6c
= -2a + 20b - 2c
