hi,
you must replace x by the number between parenthese.
I show you with the first one and let you do the second one
p(x) = 11x^5 -11x^4 - 5x^2 +15x-8
p(-4) = 11 (-4)^5 - 11 (-4)^4 -5(-4)² +15(-4) -8
p(-4) = 11 ( -1024- 256) - 5*16 -60-8
p(-4) = 11 ( -1280) -80-60-8
p(-4) = - 14080 - 148
p(-4) = - 14 228
Answer:
Step-by-step explanation:
<u>Let the integers be:</u>
<u>Their sum is 42:</u>
- x + x + 1 + x + 2 = 42
- 3x + 3 = 42
- 3x = 39
- x = 13
The numbers are: 13, 14 and 15
Alrighty, this is what I got...
b=<span><span><span>−<span>3c</span></span>+<span>2x over </span></span><span>a</span></span>
Answer:
4/3 or 1.3333333...
Step-by-step explanation:
2 x (3x + 1)-4 = 6.
6x+2-4=6.
6x+2=10
6x=8.
X= 1.3333333... OR 4/3
