I THINK the value of x = 1

Divide both sides by 2:

2x^3/2 = 2/2

x^3 = 1

Take the cube root:

x = 1^1/3

x = 1

If someone can confirm this, that would be greatly appreciated. Thank you :)

Solution set is: ( $7,\frac{13}{3}$ )

Option B is correct

Step-by-step explanation:

We need to find the solution to system of equations

$y=\frac{1}{3}x+2\\y=\frac{4}{3}x-5$

Let:

$y=\frac{1}{3}x+2\,\,\,eq(1)\\y=\frac{4}{3}x-5\,\,\,eq(2)$

Putting value of y from eq(2) into eq(1)

$\frac{4}{3}x-5=\frac{1}{3}x+2\\Combining\,\,like\,\,terms:\\\frac{4}{3}x-\frac{1}{3}x=2+5\\Taking\,\,LCM\\\frac{4x-1x}{3}=7\\\frac{3x}{3}=7\\x=7$

So, value of x=7

Putting value of x into equation 1 to find the value of y:

$y=\frac{1}{3}x+2\\y=\frac{1}{3}(7)+2\\y=\frac{7}{3}+2\\Taking\,\,LCM\\y=\frac{7+2*3}{3}\\y=\frac{7+6}{3}\\y=\frac{13}{3}$

So, value of y = $\frac{13}{3}$

Solution set is: ( $7,\frac{13}{3}$ )

Option B is correct

What are the dimensions for this triangle?

REY [17]

Answer:

2 and 2

Step-by-step explanation:

Parallel sides of rectangles are congruent, and because the other side of both rectangles is 2, the sides of the triangle are 2 because they share the side with the rectangle.

(6m^3 -16m^2 + 15m - 40) / (2m^2 + 5)

Helen [10]

6m3 - 16m2 + 15m - 40 Simplify ————————————————————— 2m2 + 5 Checking for a perfect cube :

4.1 6m3 - 16m2 + 15m - 40 is not a perfect cube

Trying to factor by pulling out :

4.2 Factoring: 6m3 - 16m2 + 15m - 40

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: 15m - 40
Group 2: -16m2 + 6m3

Pull out from each group separately :

Group 1: (3m - 8) • (5)
Group 2: (3m - 8) • (2m2)
 -------------------
Add up the two groups :
 (3m - 8) • (2m2 + 5)
Which is the desired factorization

3m-8 is the answer
