Answer:

Step-by-step explanation:

x² - x - 56 = x² - 8x + 7x - 7*8

= x*(x - 8) + 7 (x - 8)

= (x - 8) (x + 7)

If x = 10, y = 5, and z = 11, what is the tangent ratio for g°?

loris [4]

Please, find attached the image with the complete question

Answer:

$\large\boxed{\large\boxed{tan(g\º )=2}}$

Explanation:

The triangle ACB is a right triangle with these features:

x represents the opposite side to the angle g

y represents the adjacent side to the angle g

The <em>tangent ratio </em>on an angle in a right triangle is equal to the length of the leg opposite to the angle divided by the length of the leg adjacent to the angle.

Hence:

$tangent(g\º )=x/y=10/5=2\leftarrow answer$

Answer:

ad+b

give me brilliant please

Step-by-step explanation:

c−d

Step 1: Multiply both sides by c-d.

ac−ad=b

Step 2: Add ad to both sides.

ac−ad+ad=b+ad

ac=ad+b

Step 3: Divide both sides by a.

ad+b

The solution of the equation is $x=\frac{11}{7}$

Step-by-step explanation:

To simplify an equation of x

Simplify each side of the equation
Collect x in side and the numerical terms in the other side
Find the value of x

∵ The equation is $2x + \frac{1-x}{4}=3$

- Multiply all terms of the equation by 4 to cancel the denominator

of the 2nd term in the left hand side

∵ The equation is $4(2x) +4 (\frac{1-x}{4})=4(3)$

∴ 8x + (1 - x) = 12

∴ 8x + 1 - x = 12

- Add like terms

∴ (8x - x) + 1 = 12

∴ 7x + 1 = 12

- Subtract 1 from both sides

∴ 7x = 11

- Divide both sides by 7

∴ $x=\frac{11}{7}$

The solution of the equation is $x=\frac{11}{7}$
