Simplify the sum. (8u^3+8u^2+6)+(4u^3-6u+3)

rewona [7]

Answer:

$\boxed{12u^3+8u^2-6u+9}$

Step-by-step explanation:

$(8u^3+8u^2+6)+(4u^3-6u+3) = 8u^3+8u^2+6+4u^3-6u+3$

Once

$8x+4x = 12x, \text{ as } x = u^3$

$8u^3+8u^2+6+4u^3-6u+3 = 12u^3+8u^2+6-6u+3 = \boxed{12u^3+8u^2-6u+9}$

You don't need to factor.

The recipe for Cesar Salad calls for 3/4 cups of Parmesan cheese. How much is needed to make 1/2 of the recipe? HELP PLEASEEE

kramer

Answer:

To make half the recipe, we will need 3/8 Parmesan cheese.

Step-by-step explanation:

<u>We know that:</u>

Cesar Salad = 3/4 Parmesan cheese

To make 1/2 the recipe, we need to change everything in halves.

<u>Work:</u>

Cesar Salad = 3/4 Parmesan cheese
=> Cesar Salad/2 = 3/4 ÷ 2 Parmesan cheese
=> Cesar Salad/2 = 3/4 x 1/2 Parmesan cheese
=> <u>Cesar Salad/2 = 3/8 Parmesan cheese</u>

Hence, to make half the recipe, we will need 3/8 Parmesan cheese.

two towers labeled Tower A and Tower B some distance apart and a fire image at a certain distance from both towers Towers A and

astra-53 [7]

Answer:

7.0 mi

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of angle C

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

so

$A+B+C=180^o$

substitute the given values

$42^o+64^o+C=180^o\\C=180^o-106^o=74^o$

step 2

Find the measure of a

Applying the law of sines

$\frac{c}{sin(C)}=\frac{a}{sin(A)}$

substitute the given values

$\frac{10}{sin(74^o)}=\frac{a}{sin(42^o)}$

solve for a

$a=\frac{10}{sin(74^o)}sin(42^o)\\a=7.0\ mi$
