Answer:

See below

Step-by-step explanation:

a)

  • 11x^2 + x^2 = (4x + 8)(3x - 3)
  • 12x^2 = 12x^2 + 24x - 12x - 24
  • 12x - 24 = 0
  • 12x = 24
  • x = 2

b)

  • x/3 - x/9 = 6
  • 3x/9 - x/9 = 6
  • 2x/9 = 6
  • 2x = 54
  • x = 27

c)

  • 6^(x + 9) = 36^x
  • 6^(x + 9) = 6^(2x)
  • x + 9 = 2x
  • 2x - x = 9
  • x = 9

d)

  • 4/9 + 1/a = 2/3
  • 1/a = 2/3 - 4/9
  • 1/a = 6/9 - 4/9
  • 1/a = 2/9
  • a = 9/2

e)

  • √x + 3 = 6
  • x + 3 = 6^2
  • x = 36 - 3
  • x = 33

f)

1.2m - 0.2 = 3.8 + m

  • 1.2m - m = 3.8 + 0.2
  • 0.2m = 4
  • m = 4/0.2
  • m = 20

g)

  • (x + 12)^2 = 9
  • x + 12 = ± 3
  • x = ± 3 - 12
  • x = - 9, x = - 15

I will give u a five dollar gift card plz help!!!

Answer:

1. The measure of ∠WOV is 60°. You would use complementary angles that are adjacent (∠WOV, and ∠XOW)

2. The measure of ∠YOZ is 60°. You would use the vertical angles that are non-adjacent (∠WOV, and ∠YOZ). These two angles are congruent so they would have the same measure. These angles combined also create supplementary angles

3. Another way to find the measure of ∠YOZ would be to make/write an equation and solve for x. For example, (3x+30)°=60°. x would equal 10 because 10x3=30+30=60°

Step-by-step explanation:

1. Since a complementary angle would equal 90°, simply subtract 30° from 90° resulting in 60°.

2. Because vertical angles are congruent and (∠WOV, and ∠YOZ) are a pair of them, they equal the same as each other so they're both 60°.

3. You can make any equation with x included as long as it equals 60° mine was just an example you can make your own like 10x+10=60 or 4x+20=60. Also to create your equation you also need to use the angle fact of the vertical angles

Please solve the equation (15m + 3)/2 = -6
stiv31 [10]

Answer:

m = - 1

Step-by-step explanation:

Given

\frac{15m+3}{2} = - 6

Multiply both sides by 2 to clear the fraction

15m + 3 = - 12 ( subtract 3 from both sides )

15m = - 15 ( divide both sides by 15 )

m = - 1
