Step-by-step explanation:
x² + 4x - 9
= (x + 2)² - 13
a = 2, b = -13.

Step-by-step explanation:
41. √20 = √4 * 5 = √4 * √5 = 2√5
43. The sum of interior angles in a triangle is 180°, therefore, x = 180 - (75 + 64) = 41°.
45. 15 + 5(2x - 3) = 15 + 5(2x) + 5(-3) = 15 + 10x - 15 = 10x
47. Complementary angles have a sum of 90°, therefore, x = 90 - 48 = 42°.
Answer:
15.71m
Step-by-step explanation:
circumference of a circle = 2πr
where r = 2.5m
where π = 3.142
we have,
2*3.142*2.5 = 15.71m
therefore the circumference of a circle with a radius 2.5m = 15.71 m
Answer:
$2 per ride
Step-by-step explanation:
$32-$20=$12
McKenna rode 6 rides so $12 divided by 6 rides is $2 for every ride
Answer:
2 and 3
Step-by-step explanation:
prime numbers=2,3,4,5,...
taking 2 and 3
