Factor 21c+24.<br> Write your answer as a product with a whole number greater than 1.<br> use ()

Lera25 [3.4K]

Answer:

The required answer as a product with a whole number greater than 1 will be:

$21c+24=3\left(7c+8\right)$

Step-by-step explanation:

Given the expression

$21c+24$

Determining the factor

$21c+24$

Rewrite 24 as 3 · 8

Rewrite 21 as 3 · 7

so the expression becomes

$21c+24=3\cdot \:\:7c+3\cdot \:\:8$

Factor out the common term 3

$=3\left(7c+8\right)$

Therefore, the required answer as a product with a whole number greater than 1 will be:

$21c+24=3\left(7c+8\right)$

The area of the circle is 144π m2<br><br> What is the diameter of the circle?

Over [174]

Answer:

Step-by-step explanation:

Remember that

Area of Circle = $\pi r^2$

$\pi = pi \\r = radius$

They told us that for this circle, the area is $144\pi m^2$

If you put it back into the formula for area of a circle we get:

Area of Circle = $\pi r^2$

$144\pi = \pi r^2$

Divide both sides by $\pi$ .

144 = $r^2$

Now we want to solve for r (r = radius).

You need to square root each side

$\sqrt{144} = \sqrt{r^2}$

$12 = r$

So now we know the radius, $r = 12$ metres

Also remember that

Diameter = $2r$

So,

Diameter = 2 times 12 = 24 metres

Find (f*g)(x) when f(x)=x^2-7x+12 and g(x)=7/x^2-16

AleksandrR [38]

Answer:

$(f\cdot g)(x)=\dfrac{7x-21}{x+4}$

Step-by-step explanation:

$(f\cdot g)(x)=f(x)\cdot g(x)=(x^2-7x+12)\cdot\dfrac{7}{x^2-16}\\\\=7\dfrac{(x-3)(x-4)}{(x+4)(x-4)}=\dfrac{7(x-3)}{x+4}\\\\=\dfrac{7x-21}{x+4}$
