Answer:
b,d,e
Step-by-step explanation:
3(4x+3)=12x+9
b)3(3+4x)=9+12x
=12x+9
d)4x+3+4x+3+4x+3=4x+4x+4x+3+3+3
=12x+9
e)12x+9
Answer:
785
Step-by-step explanation:
flowers needed to surround the garden = circumference of the garden / space
circumference of a circle = 2nr
n = 3.14
r = radius
The radius is in ft and the space is in inches. i would convert the ft to inches to aid comparability
1ft = 12 inches
125 x 3 = 375
2 x 3.14 x 375 = 2355
flowers needed = 2355 / 3 = 785
3/4 of 100 is 75 so 3 quarters of a mile is 0.75
Answer:
the answer is d because the numbers are multiples of eachother
Step-by-step explanation:
That is height
h=16t^2+16t+480
when h=0 is when it hits the water
0=16t^2+16t+480
undistribbute 16 for ease
0=16(t^2+t+30)
16*0=0 so assume
t^2+t+30=0
factor
(t+6)(t-5)=0
set to zero
t+6=0
minus 6
t=-6
false, since you cannot have negative time
t-5=0
add 5
t=5
at t=5 she hits the water
5 seconds
