Answer:
x<1
Step-by-step explanation:
x+5<6
then subtract the 5 from both sides
and leave the inequality sign the same.
x<1

Answer:
rectangle: 2x+2 wide by 2x high
triangle: 2 high
Step-by-step explanation:
Usually, a problem like this is asking you to find dimension expressions that combine to give you the given expression. There are usually a number of possibilities. Using the designators in the attached, we would generally like to have B > C and A about the same as C. That doesn't seem possible with the given factors.
__
The given quadratic expression factors as ...
area = 4x^2 +6x +2 = (2x+2)(2x +1)
This might be written to match the area formula as ...
(2x +2)(2x +2/2)
This would give A=2, B=2x+2, C=2x, as shown in the attachment.
L= length
W= width= 9 yards
Perimeter= 72 yards
Plug in the numbers you know and solve for L.
Perimeter= 2L + 2W
72= 2L + 2(9)
72= 2L + 18
subtract 18 from both sides
54= 2L
divide both sides by 2
27= L
CHECK:
72= 2(27) + 2(9)
72= 54 + 18
72= 72
ANSWER: The length is 27 yards
Hope this helps! :)
Answer:
4/15
Step-by-step explanation:
total: 16 + 20 + 24 = 60
16 are blue
then:
the fraction of blue marbles:
16/60 = 4/15
