Answer:
Step-by-step explanation:
3.50*2= 7 dollars $2.00 *4.125=8.25 8.25+7=15.25
Last one:
In the picture a=2, b=4a, b=4•2=8
1st picture a=3, b=4a, b=4•3=12
2nd picture a=0.5, b=4•0.5=2
3rd picture a=2.5, b=4•2.5=10
4th picture a=4, b=4•4=16, but in the picture b=10 therefore, this rectangular is NOT similar to rectangular ABCD.
0 = -16t^2 -60t +54
t = 0.75 seconds
solving by the quadratic equation or graphing calculator or completing the square.
The page numbers must have a difference of one, so:
n * (n+1) = 182
n^2 + n -182 =0
Solving by the quadratic formula we see n = 13 and n+1 = 14
Answer:
A =21
B=125
