Solve each equation: -5(5x+5)+3(5x+3)=-4x-6x

Answers

Answer:

x= -1.118

Step-by-step explanation:

Firstly you need to start with the bracket

-5(5x +5) + 3(5x +3)

=( -25x +25) + (15x +9)

= -25x +25 +15x +9= -4x -6x

secondly you join the like terms together

25+9= -4x -6x +25x -15x

34= -38x

-38x ÷ 34

x= -1.118

I need help with my math

Answers

Answer:

16

Step-by-step explanation:

The formula for finding the length of a side of a right triangle is:

A^2 + B^2 = C^2 (c being the hypotenuse.)

We know what the length of the hypotenuse and one of the legs is, so we can solve by taking B^2 (the leg measuring 12) and subtracting it from C^2 (the hypotenuse) and then finding the square root of C^2.

20^2 - 12^2 = 256

or in simpler terms

20^2 - 144 = 256

Then, if we find the square root of 256 we get 16. We can check our work by substituting it back into the equation

16^2 + 12^2 = 20^2

or in simpler terms

256 + 144 = 400

So the length of the missing leg is 16. I hope this helps :)

Answer:

C. 16

Step-by-step explanation:

In order to find one side of a right triangle, given two sides, you can use the Pythagorean theorem: [tex]A^2+B^2=C^2[/tex]

We already have the values of one of the bases (12) and the hypotenuse (20), so we are looking for the second base. So, we have the values of B and C, and we need to find A.

To find A, put the values you already have into the formula as follows:

[tex]A^2+12^2=20^2[/tex]

Next, square each value:

[tex]A^2+144=400[/tex]

Subtract 144 from 400 to simplify the equation.

[tex]A^2=256[/tex]

And finally, find the square root of 256 to find A.

[tex]A=16[/tex]

Final answer:

C. 16

A ratio of two numbers is equal to 3:8. If the smaller number is 12,find the greater number.​

Answers

The other no. is:

32

As you can see that in the ratio given, 3 is the smaller no. and 12 too.

So when we divide 12 by 3, we get 4

Then to find the other no. we need to multiply 4 with 8 (which is the other no.          in the ratio given)

Therefore, we get the other no. as 32

And also when you divide 12 by 32,

You get the answer as 3 by 8 (which is the given ratio)

Hope you found this helpful!

Answers

Answer:

C

Step-by-step explanation:

We want to simplify the rational expression:

[tex]\displaystyle \frac{n^4-11n^2+30}{n^4-7n^2+10}[/tex]

First, we can factor both the numerator and the denominator. This yields:

[tex]\displaystyle =\frac{(n^2-6)(n^2-5)}{(n^2-2)(n^2-5)}[/tex]

Cancel like terms:

[tex]\displaystyle =\frac{(n^2-6)}{(n^2-2)}[/tex]

However, since we canceled a term from our expression, we must place restrictions in order to stay true to the original expression.

Rational expressions are undefined whenever the denominator equals 0. The denominator is (before canceling):

[tex](n^2-2)(n^2-5)=0[/tex]

Solve for n. By the zero product property:

[tex]n^2-2=0\text{ and } n^2-5=0[/tex]

Therefore:

[tex]n^2=2\text{ and } n^2=5[/tex]

By taking the square root of both sides (since we are taking an even root, it is required to have plus/minus):

[tex]n=\pm\sqrt{2}\text{ and } n=\pm\sqrt5[/tex]

Therefore, our fully simplified expression is:

[tex]\displaystyle \frac{n^2-6}{n^2-2}\, ,n\neq \pm\sqrt5, \pm\sqrt2[/tex]

Hence, our answer is C!

Find the value of x when (a) 9 : x : : 54 : 48 (b) 2, 6 , x are in continued proportion

Answers

Answer:

a) x = 8

b) x = 18

Step-by-step explanation:

Given that

9 : x : : 54 : 48

This may be rewritten as

9/x = 54/48

cross multiply

9 * 48 = 54 * x

Divide both sides by 54

x = 9 * 48/54

= 8

b Given that 2, 6, x are in continued proportion then

2/6 = 6/x

2 * x = 6 * 6

x = 36/2

= 18

A numerical expression is evaluated as shown.



32 ÷ {57 – 49} × 4 + 27



Step 1: 32 ÷ 8 × 4 + 27

Step 2: 32 ÷ 32 + 27

Triangle QRS has coordinates Q(-2, -2), R(0, 3), and S(4, -2) and is dilated by a scale factor of 2. Determine the new coordinates of point S', and state whether the dilation is an enlargement or a reduction

Answers

Given:

Triangle QRS has coordinates Q(-2, -2), R(0, 3), and S(4, -2) and is dilated by a scale factor of 2.

To find:

The new coordinates of point S', and state whether the dilation is an enlargement or a reduction.

Solution:

If a figure is dilated by factor k with origin as center of dilation, then

[tex](x,y)\to (kx,ky)[/tex]

Where, 0<k<1 is reduction and k>1 is enlargement.

The figure is dilated by scale factor 2 which is greater than 1, so the dilation is an enlargement. The rule of dilation is:

[tex](x,y)\to (2x,2y)[/tex]

Using this rule, we get

[tex]S(4,-2)\to S'(2(4),2(-2))[/tex]

[tex]S(4,-2)\to S'(8,-4)[/tex]

Therefore, the new coordinates of point S' are (8,-4).
