Answer:

B. 4x^2=28x-112=0.

Step-by-step explanation:

Using area=length*width, 160=(2x+8)(2x+6).

Expanding, (2x+8)(2x+6)=4x^2+16x+12x+48.

Setting this equal to 160, 160=4x^2+28x+48, or 4x^2+28x-112=0.

Solve the equations for the given variable. Then place the equations in the table under the correct solution
vekshin1

Placing the equations under the correct solution, we get

x = 3                                      x ≠ 3

-14x = -42                              -5 + x = -9

-\frac{3}{5} +x = \frac{12}{5}                          \frac{x}{3} =9

\frac{x}{4} =\frac{6}{8}                                    

x -5 = -2            

<h3>Solving Linear Equations </h3>

From the question, we are to place the equations under the correct solution

To do this, we will solve the equations one after the other

  • -14x = -42

x = -42/-14

x = 3

  • -5 + x = -9

x = -9 + 5

x = -4

∴ x ≠ 3

  • -\frac{3}{5} +x = \frac{12}{5}

x = \frac{12}{5} +\frac{3}{5}

x = \frac{12+3}{5}

x = \frac{15}{5}

x = 3

  • \frac{x}{4} =\frac{6}{8}

x=\frac{6\times 4}{8}

x=\frac{24}{8}

x = 3

  • \frac{x}{3} =9

x = 3 × 9

x = 27

∴ x ≠ 3

  • x -5 = -2

x = -2 + 5

x = 3

Hence, placing the equations under the correct solution, we get

x = 3                                      x ≠ 3

-14x = -42                              -5 + x = -9

-\frac{3}{5} +x = \frac{12}{5}                          \frac{x}{3} =9

\frac{x}{4} =\frac{6}{8}                                    

x -5 = -2

simon is making wreaths to sell .he has 60 bows, 36 silk roses and 48 silk carnation .he wantsto put the same numbers of items o
myrzilka [38]
We must assume that he must put a whole number of objects in each wreath so we must find the greatest common factor

60=2 time 2 times 3 times 5
36=2 times 2 times 3 times 3
48=2 times 2 times 2 times 2 times 3

the factors are 2 times 2 times 3 or 12
there can be 12 wreath max
we total them up and divide by 12
60+36+48=144
144/12=12
12 items per wreath

Nelson used 35% of his savings account for his class trip in may. If he used 140 from his savings account while on his class tri
Iteru [2.4K]
Ok, so I’m guessing that 35% is $140 and that the question is asking to find the total at first.
Basically,
35% -> $140
So we’re gonna find 100%
1%->140 divide by 35 which is 4
100%-> 4 x 100= $400
And that should be your answer:)
