Which of the following equation have exactly one solution?

Mathematics
1 answer:
Archy [21]3 years ago
8 0

Answer:

A, B, C all have one solution.

Step-by-step explanation:

1) Each equation in this question has one variable (x). This means that only one solution will be there.

2) Solve for x, you can cross out option D. When you subtract 52x from both sides, you're left with 52 = -78

Which is not true

3) Option A, if solved x = -65/68

4) Option B, x = 13/2

5) Option C, x = 5

All except D, have one solution, I don't know if it's a multiple choice answer but this is how I can help.

Given situation: => 18 times 4 to the second power plus (9 minus 3) to the second powerLila answers 324 while Rob answers 360 in the given problem or equation.Now, let's try to solve it to know who got the correct answer:=> 18 x 4^2 + (9 - 3)^2, since we have a parenthesis in our equation, we need to solve it first=> 18 * 4^2 + (6)^2=> 18 * (4* 4) + (6 * 6)=> (18 * 16) + 36=> 288 + 36=> 324<span>Thus Lila got the correct answer</span>

The length of a rectangle is three times its width. if the area of the rectangle is 75 in2, find its perimeter.
UkoKoshka [18]

Answer:

  40 in

Step-by-step explanation:

For a width of w, the length is 3w and the area and perimeter are ...

  A = LW = (3w)(w) = 3w^2

  P = 2(L+W) = 2(3w +w) = 8w

We are given the area, so we can find w to be ...

  75 in^2 = 3w^2

  25 in^2 = w^2 . . . . . divide by 3

  5 in = w . . . . . . . . . square root

Then the perimeter is ...

  P = 8w = 8(5 in) = 40 in
