Answer:
t = -1, 2
Step-by-step explanation:
Step 1: Define
h(t) = -5t² + 5t + 10
Step 2: Factor
h(t) = -5(t² - t - 2)
h(t) = -5(t - 2)(t + 1)
Step 3: Find roots
0 = -5(t - 2)(t + 1)
0 = (t - 2)(t + 1)
t - 2 = 0
t = 2
t + 1 = 0
t = -1
This is not possible to factor, atleast not in the format you posted it :)
Answer:
<h2>15.5 units</h2>
Step-by-step explanation:
This problem is on the mensuration of flat shapes, this time a square shape.
we know that the area of a square is given as
area= length*length
area= l^2
from the problem the area is given as
area= 240 units^2
substitute area for the area in the equation and then we solve for length we have
240= l^2
squareing both sides we have
√240= l
l= 15.49 units
to the nearest hundreths it is
15.5 units
