The answer is 61 because first you have to deal with braces than multiply and then you would subtract because of BEDMAS

A square coffee shop has sides that are 5 meters long. What is the coffee shop's area?
g100num [7]

Answer:

<h2>25m²</h2>

Step-by-step explanation:

If you want to find the area, you have to use this formula:

Formula:

LxW

L: length

W: Width

Here we have a square, and the sides are all 5 meters long, that means that we have to just do 5x5 to get the answer.

5x5=?

Hope ya remember the 5 table, lol, I know everyone does

5x5=25

so hence, your answer is 25m²

Thanks!

What are the solutions of the quadratic equation 4x2 - 8x – 12 = 0?
Juliette [100K]

Answer:

see bottom

Step-by-step explanation:

divide through by 4

x2 - 2x - 3 = 0

x2 - 3x + x - 3 = 0

(x2 - 3x) + (x - 3) = 0

x(x - 3) + 1(x - 3) = 0

(x + 1) (x - 3) = 0

x + 1 = 0 and x - 3 = 0

x = -1 and x = 3

Given that sin theta = 1/4, 0
GaryK [48]
Answer: cos(Θ) = (√15) / 4

Explanation:

The question states:

1) sin(Θ) = 1/4

2) 0 < Θ < π / 2

3) find cos(Θ)

This is how you solve it.

1) Use the fundamental identity (in this part I use α instead of Θ, just for facility of wirting the symbols, but they mean the same for the case).

(cos \alpha )^2 + (sin \alpha )^2 =1

2) From which you can find:

(cos \alpha )^2 = 1 - (sin \alpha )^2

3) Replace sin(α) with 1/4

=> (cos \alpha )^2 = 1 - (1/4)^2 = 1 - 1/16 = 15/16

=> cos \alpha =+/- \sqrt{15/16} = +/- (\sqrt{15} )/4

4) Given that the angle is in the first quadrant, you know that cosine is positive and the final answer is:

cos(Θ) = \sqrt{15} /4.

And that is the answer.
