I really need help with this, please help

As the property of tangent line of circle, the 2 right triangles ABC and ADC are congruent.

=> AB = AD or j = k

j = 25x^2 + 100x + 9

k = 21x^2 + 100x + 18

=> 25x^2 + 100x + 9 = 21x^2 + 100x + 18

=> 4x^2 = 9

=> x^2 = 9/4 = (3/2)^2

=> x = 3/2 ( -3/2 value is not valid)

Hope this helps!

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
