What is the answer to 8x-5674=[c+-4577] What is c

1 answer:

6 0

It's not completely clear what you want. Your 8x-5674=[c+-4577] has two variables: x and c. You can solve this for x or you could solve it for c, but not for both. Also, your "+-" should be written as "-" (unless you meant "plus OR minus 4577)."

So there are several different approaches, depending upon what you meant!
If you mean this: 8x - 5674=[c - 4577] and want to solve for c, do the following:
1. Remove the unnecessary brackets [ ]
2. Add 4577 to both sides the resulting equation. The result will be the expression for c that you wanted. Note that you must combine -5674 and 4577.

What are the exact solutions of x^2 − 3x − 7 = 0?

bulgar [2K]

Given:

The given equation is $x^{2} -3x-7=0$

We need to determine the exact solutions of the equation.

Exact solution:

The exact solution of the equation can be determined by solving the equation using quadratic formula,

$x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}$

From the equation the values are a = 1, b = -3 and c = -7

Thus, substituting these values in the equation, we get;

$x=\frac{-(-3) \pm \sqrt{3^2-4(1)(-7)}}{2(1)}$

$x=\frac{3 \pm \sqrt{9+28}}{2}$

$x=\frac{3 \pm \sqrt{37}}{2}$

Thus, the exact solutions of the given equation is $x=\frac{3 \pm \sqrt{37}}{2}$

Hence, Option A is the correct answer.

Find the area of the figure

lana [24]

Answer:

Below

Step-by-step explanation:

First I found the area of the portion that extends off (if that makes sense??)

It is a triangle, so use A = bh/2

A = (2)(6) / 2

= 6 cm^2

Next I found the area of the rectangle using A = LW

A = (6)(3)

= 18 cm^2

Total area = 18 + 6

= 24 cm^2

Hope this helps! Best of luck <3
