Length(l)= 2w+6
Width(w)= w
Area(A)= 140 m²
Area= l*w
140 = l*w
140= (2w+6)w
140= 2w²+6w( divide each side by 2)
70= w²+3w
w²+3w -70= 0
(^^^^^^Factor out expression)
(w-7)(w+10)= 0 (set each expression equal to zero and use the positive answer as the value for "w"(because a negative width is impossible))
w-7=0
w=7m
w+10=0
w= -10m (Impossible for a physical measurement to negative: therefore This "w" value is incorrect)
Use w=7 to find "l"
l= 2w+6
l=2(7)+6
l=14+6
l=20 m
Answer:
The dimensions of a rectangle are length and by width. For this rectangle the dimensions are 20 meters by 7 meters.
(width= 7 meters)
(length= 20 meters)
Answer:
Total number of people in the line for the dunking machine is 8.
Step-by-step explanation:
Here, let us assume the number of people in the line for hoop shoot = 12
So, the number of people in the line for cakewalk
= One- Third of the number of people in line for Hoop Shoot
= 
Also, the number of people in the line for dunking machine
= 2 x ( The number of people in line for Cakewalk)
= 2 x 4 = 8
Hence, the total number of people in line for the dunking machine is 8.
The answer will be the biggest number, by which you can divide both 28 and 32. So you can divide them in 4 groups (28/4=7 girls per group & 32/4=8boys per group)
Is there a diagram with this question?
Answer:
4.2 < sq. 5< 4.3
Step-by-step explanation:
since square root of 5 was +2 you just add +2 to both sides and you will get your answer, however it is different with different operations.
