Answer: x = 7 or x = -8

x² + x - 56 = 0

⇔ x² + 8x - 7x - 56 = 0

⇔ x(x + 8) - 7(x + 8) = 0

⇔ (x - 7)(x + 8) = 0

⇔ x - 7 = 0

or x + 8 = 0

⇔ x = 7 or x = -8

What is cos of negative pi/3?<br> what is sin of negative pi/3?
stellarik [79]
Pi/3 is equivalent to 60 degrees, as 2pi is equal to 360 degrees. cos(60) in a triangle yields 1/2, and sin(60) yields (3^(1/2))/2. Thus, -pi/3, or -60 degrees would be a fourth quadrant point on the unit circle and these values would be negative as well, at cos(-pi/3)=-1/2 and sin(-pi/3)=-(3^(1/2))/2

HELP DUE IN 10 MINUTES!! WILL GIVE BRAINLEST IF CORRECT!!!!
Harman [31]

Answer:

<u>Given equation:</u>

  • y = 10x - 32

<u>To find the y-intercept, evaluate the equation with x = 0:</u>

  • y = 10*0 - 32
  • y = 0 - 32
  • y = -32

<u>To find the x-intercept, evaluate the equation with y = 0:</u>

  • 0 = 10x - 32
  • 10x = 32
  • x = 32/10
  • x = 3.2

What is the sum 2, 3, 4, and 5?
borishaifa [10]

Answer:

14

Step-by-step explanation:

We can find the sum of these numbers by adding them together.

The cumulative rule of addition lets us add numbers together in any order we want.

So, for 2 + 3 + 4 + 5 …

2 + 3 = 5

So now we have 5 + 4 + 5

5 + 4 = 9

Now we have 9 + 5

And 9 + 5 = 14

So, your answer is 14

Hope this helps!

Step-by-step explanation:

given data  

WhatPower7(49)

to find out

Evaluate the expressions WhatPower7(49)

solution

as we know that whatpower mean exponent of equation so we get by given equation  

we know whatpower7(49) = 2

because
