Answer:

Step-by-step explanation:

$-12(x+5)=144\qquad\text{divide both sides by (-12)}\\\\\dfrac{-12(x+5)}{-12}=\dfrac{144}{-12}\\\\x+5=-12\qquad\text{subtract 5 from both sides}\\\\x+5-5=-12-5\\\\x=-17$

144=-12(x+5)

144=-12x-60

204=-12x

204/-12=x

x=-17

Find the missing dimension of each prism.

Leto [7]

Given:

Volume of the prism = 60 in³

Breadth = 2.5 in

Height = 4 in.

To find:

The length of the prism.

Solution:

We know that, volume of a prism is

$V=l\times b\times h$

where, l is length, b is breadth and h is height.

Putting V=60, b=2.5 and h=4, we get

$60=l\times 2.5\times 4$

$60=l\times 10$

Divide both sides by 10.

$\dfrac{60}{10}=l$

$6=l$

Therefore, the missing dimension of the prism is 6 in.

Which values are possible rational roots of 4x3+9x2−x+10=0 according to the rational root theorem? Select each correct answer. ±

chubhunter [2.5K]

Answer:

±2

Step-by-step explanation:

For simplicity let's take a look at a general third order polynomial:

ax^3 + bx^2 + cx + d. In this particular case,

rational roots have the form ±d/±a. Note that these are fractions/ratios. Beyond that, we factor d and choose numerators ±(all possible whole number factors of d, dividing these results by all possible factors of a.

Looking at 4x^3 + 9x^2 - x + 10 = 0, we see that d = 10 and that factors of d include ±1, ±2, ±5 and ±10. a = 4 and factors of a include ±1, ±2, ±4.

So, any rational roots of the given polynomial will stem from the possible rational roots

±1 ±2 ±5 ±10 ±1 ±2 ±5 ±10

--- , ----- , -----, ------- , ---- , ----- , --- , ------ , and so on,

±1 ±1 ±1 ±1 ±2 ±2 ±2 ±2

until you have used up all of the possible factors of 10 and all of the possible factors of 4.

Of the four possible rational roots you have shared, only ±2 (which would actually be ±2 / ±1) is acceptable.
