PLZ HELP ASAP!! WHAT IS 7- x-3 DIVIDED BY 4 + 2 ( WILL MARK BRAINLIEST)

Answer:

49+14+12= 75

Step-by-step explanation:

Answer:

(x – 1)(x^2 + x + 1) = x^3 - 1.

(x + 4)(x^2 - 4x + 16) = x^3 + 64.

Step-by-step explanation:

The identities are:

(a - b)(a^2 + ab + b^2) = a^3 - b^3   and

(a + b)(a^2 - ab + b^2) = a^3 + b^3

Answer:

Step-by-step explanation:

Answer:

x = 7.5

Step-by-step explanation:

5/6 = 10/2x-3

Solve using cross products

5 ( 2x-3) = 6*10

Divide each side by 5

2x-3 = 6*10/5

2x-3 =12

Add 3 to each side

2x-3+3 = 12+3

2x =15

Divide each side by 2

2x/2 = 15/2

x = 7.5

Answer:

2

Step-by-step explanation:

0, 1, 2, 6, 6

The median is the middle number

0, 1,     2,      6, 6

There are 5 numbers and 2 is the middle number so 2 is the median

Answer:

Median is 2

Step-by-step explanation:

Median: the middle

0,1,2,6,6

2 because you cancel the number from left to right

Answer:

Measure of the side, x = 5.25 units

Step-by-step explanation:

Figure B is a scale image of figure A.

That means figure B is an image and figure A is a pre-image.

Scale factor for the dilation from figure A to figure B = 1.75

Scale factor = [tex]\frac{\text{Side of image B}}{\text{Side of pre-image A}}[/tex]

             1.75 = [tex]\frac{x}{3}[/tex]

                  x = 1.75 × 3

                  x = 5.25 units

Therefore, measure of the side figure B is 5.25 units.

Answer: 18.66 miles per hour.

Step-by-step explanation:

The velocity of the Kayak can be written as the velocity of the kayak in still water plus the rate of the current.

If K is the velocity of the kajak, and C the velocity of the current, we have that:

When the kajak moves along with the current, for a given time T.

(K + C)*T = 10mi

when the kajak move against the current:

(K - C)*T = 4mi

now we can replace C by 8mph, and take the quotient of both equations:

((K + 8mph)*T)/(K - 8mph)*T)) = 10mi/4mi

(K + 8)/(K-8) = 10/4

K + 8 = (K- 8)*10/4

K + 8 = K*10/4 - 20

K*10/4 - K = K*6/4 = 20 + 8 = 28

K = 28*4/6 = 18.66

So the rate of the kajak is 18.66 miles per hour.

Answer:

x = 125

Step-by-step explanation:

all of the angles in a triangle must add up to 180, so 25 + 30 + x = 180. you can subtract 25 and 30 from both sides and you are left with x = 125.

hope it helps!

________________________________

Hey!!!

Solution,

X+30+25=180(Sum of angle in traingle)

or,X+55=180

or,X=180-55

X=125

The value of X is 125.

Hope it helps

Good luck on your assignment

Stay safe

Answer: always

Step-by-step explanation:

A right triangle is a kind of triangle with one right angle.

A theorem of right triangle says that :-

Hence, the statement "The altitude to the hypotenuse of a right triangle is the geometric mean between the segments on the hypotenuse."  is always true.

Thus , the correct answer is "always".

Your answer should be always :)

Answer:

Solution of given quadratic equation is

[tex]$ (\frac{8i}{3}, -\frac{8i}{3} ) $[/tex]

Step-by-step explanation:

The given quadratic equation is

[tex]9x^2 + 64 = 0[/tex]

The general form of the quadratic equation is given by

[tex]ax^2 + bx + c = 0[/tex]

Comparing the general form with the given quadratic equation

[tex]a = 9\\b = 0\\c = 64[/tex]

The solutions of the quadratic equation is given by

[tex]$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$[/tex]

Substitute the values of a, b and c

[tex]$x=\frac{-0\pm\sqrt{0^2-4(9)(64)}}{2(9)}$[/tex]

[tex]$x=\frac{\pm\sqrt{-2304}}{18}$[/tex]

[tex]$x=\frac{\pm48i}{18}$[/tex]

[tex]$x=\frac{\pm8i}{3}$[/tex]

[tex]$x=\frac{8i}{3}$[/tex]

and

[tex]$x=-\frac{8i}{3}$[/tex]

Where i represents iota which means that the given quadratic equation has complex roots.

So the solution of given quadratic equation is

[tex]$ (\frac{8i}{3}, -\frac{8i}{3} ) $[/tex]

The factored form of the given quadratic equation is

[tex]$ (x+ \frac{8i}{3}) (x- \frac{8i}{3}) = 0 $[/tex]

Answer:

First parentheses

7-3=4

4^3 / 4 x 2

Next exponents

do 4^3

4 x 4 x 4 = 64 x 4 = 256

256 / 4 x 2 is left

256 / 4 = 64

64 x 2 = 128

128

Answer:

95%

Step-by-step explanation:

you meant what is 19 in a percentage, it means that it is 19/20.  So you do 19 divided by 20.  Do the math and get .95 ..95=95% .You get this by multiplying te decimal by 100 to find the percentage  

Answer:

95%

When it says in percent, just times the fraction by 100

19/20 * 100= 95%

Or ...

You can change it to a decimal and move the decimal point back 2 spaces.

.95 = 95%

Answer:

C. x+2

Step-by-step explanation:

a factor of polynomial is where polynomial = 0

in this case it's -2 so (x+2)

Answer:

the answer will be x=-9

Step-by-step explanation:

-5(x+6)=15

-5x-30=15

-5x=15+30

-5x=45

×=-9

Answer:

[tex]x=-9[/tex]

Step-by-step explanation:

[tex]-5(x+6)=15[/tex]

Use the distributive property.

[tex]-5x-30=15[/tex]

Add [tex]+30[/tex] on both sides of the equation.

[tex]-5x=15+30[/tex]

[tex]-5x=45[/tex]

Divide [tex]-5[/tex] on both sides of the equation.

[tex]x=45/-5[/tex]

[tex]x=-9[/tex]
