Answer:
h(x) = (x + 5)² − 18
Step-by-step explanation:
h(x) = 7 + 10x + x²
h(x) = x² + 10x + 7
Complete the square. (10/2)² = 25, so:
h(x) = x² + 10x + 25 − 18
h(x) = (x + 5)² − 18
Answer:
I count 10 triangles.....
Answer:
1500 millimeters
Step-by-step explanation:
Take the common out of both numerator and denominator and cancel out the terms which are equal.
(8x³ - 2x² - 3x)/(12x²- 9x)
= x(8x² - 2x -3)/3x(4x - 3)
= (8x² - 2x -3)/3(4x - 3)
=(4x-3)(2x+1)/3(4x-3)
= (2x+1)/3
2 because 20% of 10 is 2 hence only 2 kids wore jackets
