Answer:

P = 28 cm

Step-by-step explanation:

The area of a square is

A = s^2 where s is the side length

49 = s^2

Taking the square root of each side

sqrt(49) = sqrt(s^2)

7 =s

Now find the perimeter of the square

P = 4s

P = 4(7)

P = 28 cm

Answer:

The perimeter of square is 28 cm.

Step-by-step explanation:

To find perimeter of square firstly we need to find the side of square.

using Formula

Area of square = ( side )²

49 cm² = ( side)²

taking square root of both side

√49cm² = √side²
7 cm = side

Now,

<u>Perimeter of square is</u>

Perimeter of square = 4 × side

Perimeter = 4 × 7 cm

multiply,

Perimeter = 28 cm

Hence , the perimeter of square is 28 cm.

Find the equation of the line passing<br> through the points (3,-2) and (4, 6).<br> y = 8x + [?]

Sauron [17]

Step-by-step explanation:

1.) Plug in one of the points.

y = 8x + b

6 = 8(4) + b

2.) Solve for b (or [?])

$6 = 32 + b \\ - 32 \: \: \: \: \: \: \: \: \: - 32$

32 cancels out on the right side.

Subtract 32 from 6, which is -26

3.) -26 = b

4.) Check with other point:

-2 = 8(3) + b

-2 = 24 + b

Cancel out 24 on the right side: 24-24 = 0

-2 - 24 = -26

-26 = b

Lila is building a slide for her kids. The ladder is 3 meters tall and the slide is 5 meters long. What is the distance between

lisov135 [29]

Answer:

Step-by-step explanation: For a problem like this, it’s best to use Pythagorean Theorem which is a^2+b^2=c^2 .

In this problem they gave us a and c already so we are trying to find b.

3^2+?=5^2

9+?=25

25-9=16

Find the square root of 16 which is 4

Answer: The distance between the ladder and the slide is 4 meters

Simplify the expression

finlep [7]

Answer:

$\frac{2*x - 2}{2*x} - \frac{3*x + 2}{4*x} = \frac{x - 6}{4*x}$

Step-by-step explanation:

We have the expression:

$\frac{2*x - 2}{2*x} - \frac{3*x + 2}{4*x}$

The first thing we want to do, is to have the same denominator in both equations, then we need to multiply the first term by (2/2), so the denominator becomes 4*x

We will get:

$(\frac{2}{2} )\frac{2*x - 2}{2*x} - \frac{3*x + 2}{4*x} = \frac{4*x - 4}{4*x} - \frac{3*x + 2}{4*x}$

Now we can directly add the terms to get:

$\frac{4*x - 4}{4*x} - \frac{3*x + 2}{4*x} = \frac{4*x - 4 - 3*x - 2}{4*x} = \frac{x - 6}{4*x}$

We can't simplify this anymore
