Answer:
Step-by-step explanation:
Area of the rectangle = 33 inches sq
Area of a rectangle (formula) = l*b
let the width be x
length = 2 inches + 3x = 2+3x
Area of the rectangle = l*b = 2+3x + x
33 inches sq = 2+3x + x
33 in sq = 2+4x
33/2 = 4x
16.5/4 = x
x = 4.125
width= <u>4.125 inches</u>
length = 2+3x = 2+3(4.125) = <u>14.375</u>
<u></u>
(unless your poster is 32 sq inches and you made a mistake, just replace 33 with 32 and solve it)
i know but yes i need to know it
Answer:
6 < x < 8
Step-by-step explanation:
The compound inequality in this instance represent the "and" condition, not the "or" condition.* We might solve it like this.
-47 > 1 -8x > -63 . . . . given
Multiply by -1:
47 < -1 +8x < 63
Add 1:
48 < 8x < 64
Divide by 8:
6 < x < 8
______
* You can tell this is the case by looking at the ends of the given statement:
-47 > -63 . . . . a true statement, so the solution set will be an intersection, not a union.
7/8*8/9 = (7*8)/(8*9)
Since we have an 8 both above and below, we can erase it, and so the answer is 7/9
If you put the equation into graphing calculator online or manual, you can get the graph.
