Answer:
Inequality : 4x+8 < 120
x<28
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Perimeter of a rectangle (P)= 2 length +2 width
Where:
Width = x
Length = x+4
Replacing with the values given
P = 2 (x+4) + 2x
P = 2x+8+2x
P=4x+8
Since the perimeter of the rectangle must be less than 120:
4x+8 < 120
Solving for x
4x<120-8
4x<112
x<112/4
x<28
Feel free to ask for more if needed or if you did not understand something.
Answer:
-2 ⩽ x
Step-by-step explanation:
x(x + 3) ⩽ x (2x + 5) divide both sides of tge inequality with x
x + 3 ⩽ 2x + 5 subtract x from both sides
3 ⩽ x + 5
-2 ⩽ x
IF BREADTH=b meters
THEN LENGTH=4 meter less than 3 times than the breadth of the hall.
LENGTH=3b-4 meters
the length of the rectangular hall is=3b-4 meters
Answer:
a=
or ≈ -3.66
Step-by-step explanation:
-(3a+4)=7
-3a-4=7
<em>Add 4 to both sides</em>
-3a=11
<em>Multiply both sides by -1</em>
3a= -11
Divide both sides by 3
a=
