How to solve the Quadratic formul​

Mathematics
1 answer:
Marat540 [252]2 years ago
7 0

Answer:

The answer is x=-6, x=8

Step-by-step explanation:

I recommend using the quadratic formula to solve this problem.

x^2=a

-2x=b

-48=c

Plug it into the quadratic formula.

New equation:\frac{2+-\sqrt{(-2)^2-4(1)(-48)}}{2(1)}

Simplify

Equation: \frac{2+-\sqrt{4+192}}{2}

Add 4 and 192.

Equation: \frac{2+-\sqrt{196}}{2}

Do the square root of 196.

Equation: \frac{2+-14}{2}

Make into two different equations.

Equation 1: \frac{2+14}{2}

Equation 2: \frac{2-14}{2}

Solve the two equations and you will get -6 and 8.  Hope this helps!

The volume of the triangular prism is 12.5 m³. The length is 2.5 m and the base is 2 m. What is the width?
Fantom [35]

Answer:

  (4)  5 m

Step-by-step explanation:

You want the length of side x of a right triangular prism with base edge lengths of 2.5 m and 2 m, and a volume of 12.5 m³.

<h3>Volume</h3>

The volume of the prism is given by the formula ...

  V = Bh

where B is the area of the base:

  B = 1/2bh . . . . where b and h are the leg dimensions of the right triangle

Using these formulas together, we have ...

  V = 1/2(2.5 m)(2 m)x

  12.5 m³ = 2.5x m²

Dividing by 2.5 m², we find x to be ...

  (12.5 m³)/(2.5 m²) = x = 5 m

The dimension labeled x has length 5 meters.
