Answer:

5(9b + 8)

Step-by-step explanation:

Rewrite 45 as 5 * 9

Rewrite 40 as 5 * 8

= 5 * 9b + 5 * 8

Factor out common term 5

=5 (9b + 8)

Answer:

b. 28x + 8y +2

Step-by-step explanation:

you need to distribute the -2 to all the numbers inside parentheses and then combine like terms.

-2*3x= -6x

-2*12y= -24y

-2*-5= 10 (remember neg times neg = pos)

-2*17= 34x

-2*-16y=32y

-2*4= -8

Now combine like terms

34x-6x= 28x

32y-24y=8y

10-8=2

Write the expression: 28x + 8y +2

Cone A has a radius of 2 inches and a height of 3 inches. In cone B, the height is the same, but the radius is doubled. Calculat

wlad13 [49]

Answer: Option C.

Step-by-step explanation:

Use the formula for calculate the volume of a cone:

$V=\frac{1}{3}\pi r^2h$

Where r is the radius and h is the height.

Volume of the cone A:

$V_A=\frac{1}{3}\pi (2in)^2(3in)=12.56in^3$

Volume of the cone B:

If the height of the cone B and the height of the cone A are the same , but the radius of the cone B is doubled, then its radius is:

$r_B=2r_A\\r_B=2*2in\\r_B=4in$

Then:

$V_B=\frac{1}{3}\pi (4in)^2(3in)=50.26in^3$

Divide $V_B$ by $V_A$ :

$\frac{V_B}{V_A}=\frac{50.26in^3}{12.56in^3}=4$

Therefore: When the radius is doubled, the resulting volume is 4 times that of the original cone.
