8x - 2(x + 1) = 2(3x - 1)

First, expand to remove parenthesis. / Your problem should look like: 8x - 2x - 2 = 6x - 2
Second, subtract 8x - 2x - 2 to get 6x - 2. / Your problem should look like: 6x - 2 = 6x - 2
Third, both sides are equal, so there are infinite solutions. The equation is always true.

Answer: infinite solutions

Ksenya-84 [330]

Answer:

7

Step-by-step explanation:

V = base x height

base = 5 x 6

5 x 6 = 30

V = 210

H = V/Base

H = 210/30

210/30 = 7

H = 7

FIND THE VOLUME OF A CONE 0F DIAMETER 14M AND HEIGHT 21CM. (TAKE = 3 )
Ksenya-84 [330]

Answer:

343π

Step-by-step explanation:

To find the volume of a cone, we have to use this formula

\frac{1}{3} × π × r² × h

Where 'r' is the radius and 'h' is the height

Let's start putting in the value's

We have diameter but in the formula we need the radius so we half the diameter to get the radius so 14 ÷ 2 = 7

\frac{1}{3} × π × r² × h

\frac{1}{3} × π × 7² × 21

→  Simplify the expression

\frac{1}{3}  × π × 49 × 21

→ Simplify it further

343π

Annual sales for a company are $125,000 and are increasing at a rate of 8% per year. Use an exponential function to find the ann
xxTIMURxx [149]

Answer:

sales after 5 years is $183666

Step-by-step explanation:

exponential function standard form:

a=P(1+r)^t

where p=principal(starting amount)(125,000)

r=rate of change(0.08)

t=time(5)

so

a=125,000(1+0.08)^5

a=125,000(1.08)^5

a=125,000(1.46)

a=183666
