Answer:
x=0.450765 or x=−0.950765
Step-by-step explanation:
14x² + 7x - 6
→ Find the product, sum and factors
Product = -6
Sum = 7
Factors = No factors
→ Since there are no factors utilise the quadratic formula
→ List the values of a, b and c
a = 14
b = 7
c= -6
→ Substitute into the formula
→ Simplify
x=0.450765 or x=−0.950765
Distance = speed x time
speed = distance/time
time = distance / speed
400m/36s = 11 1/9 m per second
A triangle 45 – 45 – 90 degree (or isosceles right triangle) is a triangle with angles of 45°, 45°, and 90° and sides in the ratio of 1:1:√2
if hypo = 3√2 then side = 3
answer
a = b = 3

<span>30-60-90 Triangle
</span>long leg = short leg times √3
hypo = twice the short leg
given long leg = 5√3
so
short leg = b = 5
hypo = c = 2(5) = 10
3 1/2 - 1 + 6 1/2= 9 feet is how far he walked
