Answer:
2√30 + 30√2
Step-by-step explanation:
(4√3 − 2√5)(3√10 + 5√6) simplify
=======
- (4√3 − 2√5)(3√10 + 5√6)=
- 12√30 + 20√18 - 6√50 - 10√30=
- 2√30 + 20*3√2 - 6*5√2=
- 2√30 + 30√2
rate of change is the slope
slope = (y2-y1)/(x2-x1)
m= (180-120)/(3-2)
m = 60/1
m = 60
b. point slope form
y-y1 = m(x-x1)
y-120 = 60 (x-2)
c see attached graph. x>=0 since it is hours
d the y intercept is
y -120 = 60x-120
add 120 to each side
y = 60x
The radius will be 7.25cm
The circumference will be about 45.55
The area will be about 165.13

1+12=30
Answer:
23
Step-by-step explanation:
Simplify the following:
(-66)/(-3) - 4 - -5
The gcd of -66 and -3 is -3, so (-66)/(-3) = (-3×22)/(-3×1) = (-3)/(-3)×22 = 22:
22 - 4 - -5
-(-5) = 5:
22 - 4 + 5
22 + 5 = 27:
27 - 4
| 2 | 7
- | | 4
| 2 | 3:
