Help on this anyone ?

x=8°

Step-by-step explanation:

Hi there!

We're given that angle A and B are vertical angles

Vertical angles are opposite angles that share the same vertex and are made by intersecting lines. They are congruent

so <A≅<B

We're also given that m<A=(5x-5)° and m<B=(2x+19)°

Since <A is congruent to <B, that means that (5x-5)° is equal to (2x+19)°

written as an equation, it's:

5x°-5°=2x°+19°

now solve for x

add 5 to both sides

5x°=2x°+24°

subtract 2x from both sides

3x°=24°

divide both sides by 3

x=8°

Hope this helps! :)

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
