x=-8 or x=-1 (first option)
Step-by-step explanation:
now expand the bracket on the right
now make it a quadratic equation:
Answer:
x=15
Step-by-step explanation:
they all add up to 360degrees
Answer:
15
Step-by-step explanation:
Cross multiply
3 times 20 = 60
4 times x = 4x
now your left with
60= 4x
divide 4 on both sides
15 = x

Step-by-step explanation:
Find the complete question below;
Given the height modeled by the function;
h(t) = 5 + 98t-4.9t²
when t = 0
h(0) = 5 + 98(0)-4.9(0)²
h(0) = 5
when t = 5
h(5) = 5 + 98(5)-4.9(5)²
h(5) = 5 + 490 - 122.5
h(5) = 372.5
when t = 10
h(10) = 5 + 98(10)-4.9(10)²
h(10) = 5 + 980 - 490
h(10) = 495
when t = 15
h(15) = 5 + 98(15)-4.9(15)²
h(15) = 5 + 1470 - 1,102.5
h(15) = 372.5
when t = 20
h(10) = 5 + 98(20)-4.9(20)²
h(10) = 5 + 1960 - 4.9(400)
h(10) = 1965- 1960
h(10) = 5
