Expand and Simplify:<br> (3x + 5) (x - 2)<br> -Please Help! Due in for 4:30pm! Xx

Jobisdone [24]

Answer:

I know this is really late but if anyone else needs help I hope this will help those people.

Step-by-step explanation: so expand (3x+5) (X-2) first apply FOIL method: (a+b) (c+d)= ac + ad +bc + bd..... a= 3x, b=5, c=x, d= -2. our end product would be 3xx+3x(-2) + 5x + 5(-2).

Then apply minus-plus rules: +(-a)= (-a)...... we would end up with 3xx-3 times 2x + 5x - 5times 2.

next simplify until we end up with 3x^2 - x- 10

Not 100% sure if this is what your looking for but this is my best educated guess from the question asked.

A prism with a base area of 5 ft² and a height of 10 ft is dilated by a factor of 65 . What is the volume of the dilated prism?

mina [271]

Answer:

The volume of the dilated prism is $86.4ft^3$ .

Step-by-step explanation:

The original prism has base area $5ft^2$ and a height of $10ft$ .

The volume of the original prism is $v=5\times 10=50ft^3$ .

The prism is dilated by a scale factor of $k=\frac{6}{5}$ .

To find the volume of the dilated prism, we multiply the volume of the original prism by $k^3=\frac{216}{125}$ .

$V=\frac{216}{125} \times 50ft^3$

$\Rightarrow V=86.4ft^3$

Can somebody answer this (on the picture) algebra question please

zheka24 [161]

I am torn between B and D because increased means add, but I am going to go with B 1 - 3n. I choose B because in the D option it decreases not increases.

So the answer is B.) 1 - 3n
Hope this helps! - Alyssa

What is the measure of arc CD?

CaHeK987 [17]

Option C:

The measure of arc CD is 40°.

Solution:

Given data:

m∠X = 11° and m(arc AB) = 18°

To find the measure of arc CD:

We know that,

<em>Angle formed by two intersecting secants outside the circle is equal to half of the difference between the intercepted arcs.</em>

$$m \angle X =\frac{1}{2}({arc \ CD}-{arc} \ AB)$

$$ 11^\circ =\frac{1}{2}({arc} \ CD-{18^\circ})$

Multiply by 2 on both sides.

22° = arc CD - 18°

Add 18° from both sides.

40° = arc CD

Switch the sides.

arc CD = 40°

Hence the measure of arc CD is 40°.

Option B is the correct answer.
