-7b^3 / 7b-
-7 / 7 = -1
b^3 / b (^1) = b^2

Note that if there is no exponent after a variable, it's automatically a 1, also, when dividing exponents, you are basically subtracting...
Thus b^3 / b actually equals b^3 - b^1

Firstly, you need to multiply -1 by b^2 (since those two were originally together)
= -1b^2

Now you need to divide 28b^2 by 7b,

28 / 7 = 4 and b^2 / b = b
4 * b = 4b

So, your answer should be
-b^2 + 4b

The equation y^2+8y−x+18=0 represents a parabola. Drag and drop the expressions into the boxes in the equation to rewrite the eq

mario62 [17]

Answer:

The equation of parabola is standard form is $x=\left(y+4\right)^2+2$

Step-by-step explanation:

Given equation of parabola is,

$y^2+8y-x+18=0$

In order to find the equation of parabola in standard form, eliminate x from left side of equation and use completing square method to find the equation.

First step is to add x on both side of equation.

$y^2+8y-x+18+x=0+x$

$y^2+8y+18=x$

Rewriting,

$x=y^2+8y+18$

Now applying completing square method as follows.

Following are the steps for calculation of this method.

Find the last term of above equation by using below formula,

$Last\:term\:of\:square=\left(\dfrac{coefficient\:of\:y}{2}\right)^{2}$

Now coefficient of y is 8.

$\therefore Last\:term\:of\:square=\left(\dfrac{8}{2}\right)^{2}$

Simplifying,

$Last\:term\:of\:square=\left(4\right)^{2}$

$Last\:term\:of\:square=16$

Second step is to add and subtract the last term.

$x=y^2+8y+18+16-16$

Rewriting,

$x=y^2+8y+16+18-16$

Since $\left(a+b\right)^{2}=a^{2}+2ab+b^{2}$

Using above formula,

$x=\left(y+4\right)^{2}+2$

Therefore, the equation of parabola in standard form is $x=\left(y+4\right)^{2}+2$

Find the value of n .<br> 6/n = 24/28<br> y = ___.

il63 [147K]

Answer:

$n=7$

Step-by-step explanation:

Cross multiply, isolate the variable, and divide by the coefficient to solve.

$\frac{6}{n}=\frac{24}{28} \\ \\ 24n=168 \\ \\ n=7$

Plug back in to check.

$\frac{6}{7}=0.857142857 \\ \\ \frac{24}{28} =0.857142857$

Help pls!!<br><br> Use 3.14 for pi.

krok68 [10]

<h3>Find the area of the circle</h3>

To find the area, we take into account that your data is:

r = 6 cm
π = 3.14

To calculate the area of the circle, we use the following formula:

Area: π * r²

We substitute the data in the formula, and we begin to solve.

A = 3.14 * (6 cm)²

taking the square root

A = 3.14 * 36 cm²

Multiply the two numbers

A = 113.04 cm²

Therefore, the area of the circle is 113.04 cm². The correct alternative is option "A".
