The second 2m=8
2m=12-4

Nikitich [7]2 years ago

Answer:

B) 2m = 8

Step-by-step explanation:

4m − 2m + 4 = −1 + 13

Here we have to solve for "m"

The given steps are:

Step 1: 4m − 2m + 4 = −1 + 13

Step 2: 4m − 2m + 4 = 12

Step 3: 2m + 4 = 12

The next step would be subtract 4 from both sides,

Step 4: 2m + 4 - 4 = 12 - 4

2m = 8

Therefore, the answer is B) 2m = 8

Please help: Find the volume of the solid. Use 3.14 for π.
Kazeer [188]

Answer:

The volume of the solid is 420m³

Step-by-step explanation:

The area of any pyramid is "1/3 · B · h", where B is the area of the base, and h is the height.

Knowing this we just need to solve for a couple of things.

First, and the easiest is the height of the triangle which (thankfully) is given to us. The height is 15m, which plus one number into our equation.

1/3 · B · 15

Second, we need to find the area of the base of the pyramid. That's done easily by finding the area of a triangle ( \frac{base * height}{2} → \frac{24*7}{2} → \frac{168}{2} → 84) giving us 84 units. This puts another number into our equation.

1/3 · 84 · 15

Now that we have all of the parts to our equation, we can solve it.

1/3 · 84 · 15

1/3 · 1260

420

The volume of the solid is 420m³

Nick's rectangular bedroom has a length of (2x−5) and a width of (x+1). Which equation describes the area, A, of Nick's bedroom
Mrac [35]

Answer:

A = 2x²-3x-5

Step-by-step explanation:

Given that,

The length of the bedroom, l = (2x-5)

Width of the bedroom, b = (x+1)

We need to find an equation for the area of the bedroom. We know that,

Area of a rectangle = lb

Put all the values,

A = (2x-5)(x+1)

= 2x²+2x-5x-5

= 2x²-3x-5

Hence, the area of the bedroom is equal to 2x²-3x-5.
