Answer:
19 feet
Step-by-step explanation:
The perimeter is calculated by multiplying the sum of length and width by 2
width is 3 less than length so if we call the width x the length would be x + 3
2×(x + x + 3) = 4x + 6 and
4x + 6 = 70 subtract 6 from both sides
4x = 64 divide both sides by 4
x = 16
The length is x + 3 so the answer is 19 feet
Answer:
2 months
Step-by-step explanation:
you can set up equations for each sister:
(Sarah) y = 3x + 30
(Anna) y = -2x + 40
you can graph them to find where they intersect (2,36) or:
you can set them equal to each other like the following:
3x + 30 = -2x + 40
5x = 10
x = 2
Answer:
Wait..Where's the question?
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given that:

if we assume that x is zero, then
,
i.e the radius of the circle goes from -6 to +6, Similarly, if we assume that z is zero, then
,
,
. This implies that
describes the circle with radius 6
is an equation at region which consist of those points whose distance from the centre is at least with radius -6 and at most 6.
Therefore, the region is the solid cylinder of radius 6, where the Y axis is also the axis of the cylinder.
