Answer:

b = 28

Step-by-step explanation:

Given

a(7x+2)=bx+8

=> 7ax + 2a = bx + 8

in both the equation there is a term containing x and a term not containing x.

since value of both equation is equal. hence

term containing x on both side will be equal to each and

term independent of x will be equal in both the equation

thus

7ax = bx

2a = 8

=> a = 8/2 = 4

now, plugging a = 4 in 7ax = bx

7*4x = bx

=> b = 7*4x/x = 28.

Thus, value of b is 28.

Shape A has a perimeter of 36 feet and on of the side lengths is 12
Maru [420]

The perimeter of a shape is the sum of its side lengths

The corresponding side length for shape B is 20 feet

<h3>How to determine the length</h3>

The length-perimeter ratio is given as:

Ratio = Length : Perimeter

For both shapes, we have:

12 : 36 = Length : 60

Express as fraction

\frac{12}{36} = \frac{Length}{60}

Multiply both sides by 60

Length = \frac{12}{36} * 60

Length =20

Hence, the corresponding side length for shape B is 20 feet

The square of a number decreased by the square of one half the number is 108. What is the number?
Shkiper50 [21]
Let the number be n.  Then

n^2 - (n/2)^2 = 108.
                                          n
From this we get    n^2 - (---- )^2 = 108.
                                          2

 Mult. both terms by 4, with the result   4n^2 - n^2 = 432

Then 3n^2 = 432, and n^2 = 144.  n could be either 12 or -12.  You must check both answers by subst. them into the original equation.
