Please show me step by step how to solve this problem 3(-8+4v)=8v ?
Nadusha1986 [10]
So we know that:
3(-8 + 4v) = 8v
To find v, first simplify the left hand side:
-24 + 12v = 8v
Then group the "v's" over to the right:
-24 = -4v
-6 = -v
So v = 6

Hope this helped

Angelica calculated the distance between the two points shown on the graph below. (1st picture)
Alex Ar [27]
Use the distance formula to find the value of the side lengths.
d=√((x1-x2)²+(y1-y2)²

d of side AC is 6

d of side CB is 10 

Angela's use of the Pythagorean Theorem of 10²+6²+c² is incorrect; she put the right values in the wrong spots, the formula needed is:
6²+10²=c²

Option C- Angelica's side lengths were too long.

The length of a concrete slab is three more than three times the width. It's area is 330 square feet. What is the length of the
marin [14]

Answer:

Width: 10.5 feet

Length: 31.5 feet

Step-by-step explanation:

Let x represent width of the concrete slab.

We have been given that the length of a concrete slab is three more than three times the width. So length of the slab would be 3x.

We are also told that the area of slab is 330 square feet. We can represent this information in an equation as:

x\cdot 3x=330

3x^2=330

x^2=\frac{330}{3}

x^2=110

Now, we will take square root of both sides.

\sqrt{x^2}=\sqrt{110}

x=10.488\approx 10.5

Therefore, the width of slab is approximately 10.5 feet.

The length of the slab would be 3x\Rightarrow3(10.5)=31.5.

Therefore, the length of slab is approximately 31.5 feet.
