Answer:
9x+7
Step-by-step explanation:
Let's simplify step-by-step.
4x+17+5x−10
=4x+17+5x+−10
Combine Like Terms:
=4x+17+5x+−10
=(4x+5x)+(17+−10)
=9x+7
Answer:
66
Step-by-step explanation:
since BD and BC are congruent, angle C and angle D are equal. this means 6x-9=3x+24. If you solve this equation you get x=11. If you plug it into either 6x-9 or 3x+24 you get 57. 180-(57+57)=66
If the shapes are similar, the correspondent sides are in proportion:
Let's plug the values and solve for x:
Multiply both sides by x to get
The only feasible solution, though, is 
, because it wouldn't make sense to have negative lengths.
The reasonable amount of time it would take for him to run all five blocks is 19 minutes
The expression x³ - 64 can be rewritten using difference of cubes is; (x - 4)(x² + 4x + 16)
<h3>How to write an expression as difference of cubes?</h3>
Difference of cubes can be rewritten in the form of;
a³ – b³ = (a – b)(a² + ab + b²)
So in this question, we are given;
x³ - 64 = x³ - (4)³
where a = x and b = 4
This gives us;
(x - 4)(x² + 4x + 4²)
⇒ (x - 4)(x² + 4x + 16)
