Find the perimeter of a rectangle with length 7x - 2 and width 5x^2 + 1.
stealth61 [152]

Answer:

10x^2 + 14x - 2

Step-by-step explanation:

So for the perimeter, you have to solve 2(7x-2) + 2(5x^2+1)

So distribute the 2s on both s we get 14x - 4 + 10x^2 + 2

This in standard form is 10x^2 + 14x - 2

The inequality 2x+2≤x+4≤3x+4 means that x is in the closed interval [A,B]
Alex_Xolod [135]

Answer:

Step-by-step explanation:

2x+2≤x+4≤3x+4

means : 2x+2≤x+4  ...(1) and x+4≤3x+4

(1) : 2x-x≤4-2   so : x≤2....(*)

(2) :3x+4 ≥x+4    .... 3x-x ≥ 0    so: x≥0 ....(**)

by (*) and (**) : 0≤x≤2   so : A=0  and B = 2

Which line has a slope of 1/2 and goes through the point (2,4)?
Pani-rosa [81]
The line equation for its slope and one point is:
y - y1 = m(x - x1)
m is the slope, x1, y1 are the point coordinates, so lets substitute:
y - 4 = (1/2)(x - 2)
y = <span>(1/2)x + 3</span>
