Answer:

A. 6

Step-by-step explanation:

a^{2}+b^{2}=c^{2}

3^{2}+5^{2}=c^{2}

3^{2}=9

5^{2}=25

25+9=34

\sqrt{34}= 5.83

If a b and c are three different numbers which of the following equations has exactly one solution?
Mrrafil [7]

Option B is correct.

Step-by-step explanation:

We need to identify which of the following equations has exactly one solution.

We will solve each equation to find the answer

A. ax+b=ax+b

Solving and finding value of x:

ax+b=ax+b\\ax-ax=b-b\\0=0

This equation has infinite number of solutions because both sides are equal to 0

B. ax=bx+c

Solving and finding value of x:

ax=bx+c\\ax-bx=c\\x(a-b)=c\\x=\frac{c}{a-b}

This equation has exactly one solution

C. ax+b=ax+c

ax+b=ax+c\\ax-ax=c-b\\0=c-b

This equation has no solution because both sides are not equal.

So, Option B is correct.

the length of a rectangle is 4 more than the width. if the perimeter of the rectangle is 57.2 inches find the length and the wid
dusya [7]

Answer:

Length = 16.3 in and Width = 12.3 in

Step-by-step explanation:

Let's name L the length and W the width of the rectangle. We can then write equations describing the statements given:

"<em>the length of a rectangle is 4 more than the width</em>"

L = W + 4

"<em>the perimeter of the rectangle is 57.2 inches</em>"

2 L + 2 W = 57.2

(where we used the formula for the perimeter of the rectangle equal to twice the rectangle's length plus twice the rectangle's width)

Now we use the first equation to substitute for L in the second one:

2 ( W + 4) + 2 W = 57.2

use distributive property to remove parenthesis

2 W + 8 + 2 W = 57.2

combine like terms

4 W + 8 = 57.2

subtract 8 from both sides

4 W = 57.2 - 8 = 49.2

divide both sides by 4 to isolate W

W = 49.2 / 4 = 12.3 in

Now we use this result in the first equation we wrote, to find L

L = W + 4 = 12.3 + 4 = 16.3 in

Therefore : Length = 16.3 in and Width = 12.3 in
