Sorry there is no table or picture to show the subjects ;-;
Step-by-step explanation:
Formula for the perimeter of a rectangle = 2(L + W).
let the width be x
length = 2 + 2x
substitute respectively
52 = 2(2 + 2x + x)
52 = 2 (2 + 3x)
52 = 4 + 6x
52 - 4 = 6x
48 = 6x
divide both sides by 6
48/6 = 6x/6
8 = x
width = 8
length = 2 + 2x = 2 + 2(8) = 2 + 16 = 18
Answer
(f ο g)(2)= 1/17 =0.058 and (f+g)(2)= 17.5
Step-by-step explanation:
f(x)=1/x ; f(2)=1/2
g(x)=4x+9 ; g(2)=4(2)+9
As,
1. (f ο g)(x)=f(g(x)) (Composite Function)
(f ο g)(2)=f(g(2))=f(4(2)+9)=f(8+9)=f(17)=1/17
=0.058 (in decimal)
2. (f+g)(x)= f(x)+g(x) (Sum of Functions)
(f+g)(2)=f(2)+g(2)=1/2 +(4(2)+9)=1/2+(8+9)=1/2+17 (taking L.C.M)
=[1+17(2)]/2=(1+34)/2=35/2
=17.5 (in decimal)
Answer:
Step-by-step explanation:
It takes Lucas 3 hours to cycle from his home to his friend’s village:
3 hours • (a certain speed) = distance in miles
If he travels 5mph slower, it will take him 1.5 hours longer:
4.5 hours • (the same speed - 5mph) = the same distance in miles
4.5 • (x - 5) = 3x
4.5x - 22.5 = 3x
1.5x = 22.5
x = 15mph
3hours • 15mph = 45 miles
