Answer:
x = -3.5 ± √17/2
or
x = -1.44, -5,56 to the nearest hundredth.
Step-by-step explanation:
x^2 = –7x – 8
x^2 + 7x + 8 = 0
Using the quadratic formula:
x = [-7 ± √(7^2 - 4*1*8)] / 2
x = -3.5 ± √17/2

Answer:
E = 58
F = 32
G = 90
Step-by-step explanation:
3x + 31 + 5x -13 + 90 = 180
3x + 31 + 5x -13 = 90
8x = 90 - 31 + 13
8x = 72
x = 72 / 8
x = 9
E = 3(9) + 31 = 27+31 = 58
F = 5(9)-13 = 45 - 13 = 32
G = 90
Answer:
22 November
Step-by-step explanation:
First we have to find the total length she swims in 1 day
= 2(length of the swimming pool) x no. of lengths she swims in 1 day
=2x30x20
=120m she covers in 1 day
10km = 10,000m
no of days= total distance/ distance she covers in 1 day
=10000/120
=83.3 days
