I need solving 4.8 (x+4)=2.6
victus00 [196]
<span>4.8 (x+4)=2.6
Use distributive property
4.8x + 19.2= 2.6
Subtract 19.2 from both sides
4.8x = -16.6
Divide 4.8 on both sides so that the only thing remaining on the left side is the variable x.
Final Answer: x = -3.458</span>

Harper's house is 30 feet wide and 45 feet long. On a scale drawing, the house is 4 inches wide and 6 inches long, and Harper's
Gnom [1K]
So 30 ft is equal to 4 Inc on scale !
therefore 1.2 on scale will be (30/4)×1.2= 9 ft wide !!

6 Inc on scale is equal to 45 feet on actual
so 1.6 will be (45/6)×1.6= 12 ft long


so answer is 9 ft wide and 12 ft long !!

Questions 7 and 8 multiple choice
Nitella [24]

Problem 7

<h3>Answer: Choice A) 7</h3>

--------------------------------------

Work Shown:

p(x) = x^4+x^3-kx-x+6

If (x-2) is a factor of p(x), then x = 2 is a root of p(x). This is a special case of the remainder theorem.

This means p(2) = 0

Replace every x with 2 and solve for k

p(x) = x^4+x^3-kx^2-x+6

p(2) = 2^4+2^3-k(2)^2-2+6

p(2) = 16+8-4k-2+6

p(2) = 28-4k

0 = 28-4k .... replace p(2) with 0

4k = 28

k = 28/4

k = 7

The polynomial

p(x) = x^4+x^3-7x^2-x+6

has the factor (x-2)

============================================

Problem 8

<h3>Answer: D) 40</h3>

--------------------------------------

Work Shown:

Check out the diagram below to see the synthetic division table. We're after the remainder which is highlighted in yellow.

An alternative is to use direct substitution

p(x) = 2x^4+4x^3-x^2-5

p(-3) = 2(-3)^4+4(-3)^3-(-3)^2-5 ... replace every x with -3

p(-3) = 2(81)+4(-27)-9-5

p(-3) = 162-108-9-5

p(-3) = 40  

This helps confirm we got the right remainder and the right answer.
