Factor 42 into factor pairs and add them and see which ones add to -13
remember both must be negative
-1-42=-43 nope
-2-21=-23 nope
-3-14=-17 nope
-6-7=-13 yep
the numbers are -7 and -6
(9/3+1/3) x (15/3+1/3) = 10/3 x 16/3 = 160/9 square yards
1 square foot = 1/9 square yards
160/9 square yards x 9 = 160 square feet
4.10$ x 160 = 656$
Step-by-step explanation:
h = -490t² + 1470t
When h = 980:
980 = -490t² + 1470t
Simplifying:
0 = -490t² + 1470t - 980
0 = t² - 3t + 2
Factoring:
0 = (t - 1) (t - 2)
t = 1, 2
There are two solutions because the rocket first reaches the height of 980 cm as it's going up at 1 second, then it reaches that height again as it's coming down at 2 seconds.
