Answer:
0.25 book/hour
Step-by-step explanation:
(1/6)/(2/3)=x/1
*Simplify the equation
1/4=x
*Rearrange the equation
x=1/4
x=0.25 book/hour
<span> x^4 - 8x^3 + 17x^2 - 8x + 16 = 0
x^4 - 8x^3 + 16x^2 + x^2 - 8x + 16 = 0
x^2(x^2 - 8x + 16) + (x^2 - 8x + 16) = 0
(x^2 + 1)(x^2 - 8x + 16) = 0
(x^2 + 1)(x - 4)^2 = 0
x^2 + 1 = 0 or x - 4 = 0
x^2 = -1 or x = 4
x = +/- i or x = 4
Technically there are 2 imaginary solutions and 1 real solution.
However, since the real solution occurs twice (multiplicity 2), you
could say there are 2 real solutions (although they're the same). So the
second answer would apply. </span>
Answer:
B
Step-by-step explanation:
25y² - 16 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
Given
25y² - 16
= (5y)² - 4²
= (5y - 4)(5y + 4) → B
Answer is c divide 15 by 2 =7.5 per person divide 20 by 3 = 6.666 per
Then divide 35 by 4 and you get 8.75 per person
Question 4
4(2x +5)
What you are going to do is called the distributive property.
First you are going to multiply the 4 and the 2 and you would get 8x.
Second you are going to multiply the 4 and the 5 and you would get 20.
Answer is 8x+20.
