The original square has the area (8 in)^2 = 64 in^2.

If we mult. this area by 36, we get the area of a larger square 2304 in^2.

The new side length is sqrt(2304 in^2), or 48. In other words, the original square has side length 8 in, but the 'new' square has side length 48 in.

Hello!

<h3><em><u>Answers</u></em></h3>

1. $\frac{7}{10} + \frac{2}{10} = \frac{9}{10}$ Simplest form: $\frac{9}{10}$

2. $\frac{13}{16} + \frac{2}{16} = \frac{15}{16}$ Simplest form: $\frac{15}{16}$

3. $\frac{4}{5} + \frac{1}{5} = \frac{5}{5}$ Simplest form: $\frac{1}{1}$

4. $\frac{7}{15} + \frac{2}{15} = \frac{9}{15}$ Simplest form: $\frac{3}{5}$

5. $\frac{9}{20} + \frac{3}{20} = \frac{12}{20}$ Simplest form: $\frac{3}{5}$

6. $\frac{5}{8} + \frac{1}{8} = \frac{6}{8}$ Simplest form: $\frac{3}{4}$

Mathematics <br><br> Solving inequality

lions [1.4K]

Answer:

x _> 9 I dont have the symbol on my phone so I just put the greater than sign there

Step-by-step explanation:

1. Subtract 3 from both sides

5x > 48 - 3

2. simplofy 48 - 3 to 45

5x > 45

3. Divide both sides by 5

x > 45/5

4. Then simplify 45/5 to 9 which gives us the answer

And again I dont have the sign thats why I used the greater than sign

A triangle has side lengths of (7.8v+2.6)(7.8v+2.6) centimeters, (5.3v+4.5)(5.3v+4.5) centimeters, and (2.4w-6.7)(2.4w−6.7) cent

Citrus2011 [14]

Given:

A triangle has side lengths of (7.8v+2.6) centimeters, (5.3v+4.5) centimeters, and (2.4w-6.7) centimeters.

To find:

The expression which represents the perimeter, in centimeters, of the triangle.

Solution:

We know that

Perimeter of a triangle = Sum of length of all sides of the triangle

$Perimeter=(7.8v+2.6)+(5.3v+4.5)+(2.4w-6.7)$

Now, combine like terms.

$Perimeter=(7.8v+5.3v)+(2.4w)+(2.6+4.5-6.7)$

$Perimeter=13.1v+2.4w+0.4$

Therefore, the expression for perimeter, in centimeters, of the triangle is $13.1v+2.4w+0.4$ .
