x<12
Answer:
x<12
V=12000 sq feet
Forgive me if I’m wrong I’ll redo it if so
The formula for volume is Length x width x height.
Bottom: 18 * 12 * 8 = 1728 cubic centimeters.
Middle: 12 * 8 * 6 = 576 cubic centimeters.
Top = 4 *4*4 = 64 cubic centimeters.
Total: 1728 + 576 + 64 = 2368 cubic centimeters.
Answer:
33.7 m
Step-by-step explanation:
tan ACB = AB/AC
tan 34 = AB/50
AB = 50tan(34)
AB = 33.7254258421
1) x^2=64 is the same as x=the root of 64 which gives us: (+-)8
2) here you must us pq-formel as:
5m^2-5m=60
5m^2-5m-60=0
(m^2-5m-60)/5=0
m^2-m-12=0
m=0,5(+-) the root of 0,25+12
m=0,5(+-)3,5
m1=0,5+3,5
m2=0,5-3,5
15) x^2=7x
x^2-7x=0 here there is two x, so:
x(x-7)=0
x1=0
x2=7

Here you can only use PQ formula in all the others, just as I did in the question number 2</span>
