A rectangle has an area of 248m2.
One of the sides is 4m in length.
Work out the perimeter of the rectangle.

Answers

Answer 1

Step-by-step explanation:

In a rectangle

Area (A) = 248 m²

length (L) = 4 m

breadth (b) = ?

We know

A = L * b

248 = 4 * b

b = 62 m

Now

Perimeter of the rectangle

= 2 ( L + b)

= 2 ( 4 + 62)

= 2 * 66

= 132 m

Hope it will help :)

Answer 2

Answer:

first we have to get the width.

A=L*w

so, A =L *W

L L

W=A

L

248m²=4m*W

248m²=4m*w

4m 4m

w=248m²

4m

w=32m

now we can find the perimeter.

p=2(L+w)

p=2(4m+32m)

p=2(36m)

p=72m

there for the answer is 72m

The completed table of values for the equation y = 3x - 4 includes the following points: (-2, -10), (-1, -7), (0, -4), (1, -1), and (2, 2). These points represent the corresponding values of y when different values of x are substituted into the equation.

To complete the table of values for y = 3x - 4, we can assign different values to x and calculate the corresponding values of y. Let's choose a few values for x and find the corresponding y-values:

x                y = 3x - 4

-2                  -10

-1                   -7

0                   -4

1                    -1

2                     2

By substituting these x-values into the equation y = 3x - 4, we can calculate the corresponding y-values. Therefore, the completed table of values for the given equation is:

x                  y = 3x - 4

-2                          -10

-1                          -7

0                         -4

1                          -1

2                           2

These values represent points on the graph of the equation y = 3x - 4.

Is y=x^2+7 a linear equation?

Answers

Answer:

No, it is not a linear equation

Step-by-step explanation:

This equation contains the term x², meaning that it is a quadratic function (parabola)

So, it is not a linear equation.

If it were a linear equation, x would not be squared, and the equation would have been in y = mx + b form.

The answer is no, it is not a linear equation.

Answer:

Given :-

[tex] \large \sf \bullet \: y = {x}^{2} + 7[/tex]

To Find :-

Is it a linear Equation

Solution :-

We may notice that

x has power as 2.

Have a common difference Have a common factor Have a linear first difference

============================================================

Explanation:

Linear functions, such as y = 2x+5, have a common difference. In that example, the common difference would be 2 since we add 2 to each term to get the next one. Consider when x = 1 and that leads to y = 7. Then when x = 2, we have y = 9. Then when x = 3, we have y = 11, and so on. The sequence of y values {7,9,11,...} shows we add 2 each time.

------------------

Exponential functions have us multiply the previous term by some common factor to get the next term. A sequence like {2,6,18,...} has us multiply by 3 each time and the exponential function modeling this sequence is y = 2(3)^(x-1) where x is a natural number. So this is an example showing that exponential functions have a common factor, or we can call this a common ratio.

------------------

Quadratic functions are a bit strange.

Let's consider the quadratic of y = x^2. The sequence of y values it generates is {1,4,9,16,25...} for positive integers x = 1, 2, 3, 4, 5....

Let's subtract the adjacent terms (larger - smaller)

4-1 = 39-4 = 516-9 = 725-16 = 9

Note the results of 3,5,7,9 are in a linear sequence (we're adding 2 to each increment value, so the next increment would be +11). We can consider this a linear first difference.

------------------

For any of these functions, I'm restricting x to be an integer and x = 1 is the smallest input possible.

What is the solution set for −4x − 10 ≤ 2

Answer:

x≥−3

Step-by-step explanation:

−4x−10≤2

Add 10 to both sides.

−4x≤2+10

Add 2 and 10 to get 12.

−4x≤12

Divide both sides by −4. Since −4 is negative, the inequality direction is changed.

x≥12/-4

Divide 12 by −4 to get −3.

x≥−3

The answer is x ≥ -3

Step by step explanation:

-4x - 10 ≤ 2

-4x ≤ 2 + 10

-4x ≤ 12

-4x/-4 ≥ 12/-4

x ≥ -3

Remember when you times or divide with a negative number, the sign changes.

How to get y and z please help I really need this

Answers

Answer:

y = 102, z = 70

Step-by-step explanation:

z and 110 are adjacent angles and supplementary, sum to 180° , so

z = 180 - 110 = 70

The sum of the interior angles of a quadrilateral  = 360°

sum the given angles and equate to 360

99 + 89 + 70 + y = 360, that is

258 + y = 360 ( subtract 258 from both sides )

y = 102
