Add 2 to both sdies
now if we can facor, then if
xy=0 then x and/or y=0
note:xy=x times y and x(y) =x times y
x^2+3x+2=0
what 2 number multiply to get 2 and add to get 3
the numbers are 2 and 1
(x+2)(x+1)=0
set them to zero
x+2=0
subtract 2
x=-2
x+1=0
subtract 1
x=-1
x could be -1 or -2
x=-2, or -1
Answer:I think its D
Step-by-step explanation:
Answer:
120 m^2
Step-by-step explanation:
Length of the room = 10 m
Breadth of the room = 12 m
We know that, Area = Length * Breadth
Hence,
Total Area of carpet needed to cover the floor of the room = 12 * 10 = 120 m^2
Answer:
8h-3>3h +2
8h-3h>2+3
5h>5
h>1
don't forget to draw your number line
pls make me the brainliest
We use the trigonometric function for this case. An escalator is an inclined path. We form a right triangle since we have given the value of the height. The height from the first floor to second floor is called the adjacent while the travelled distance of the people is called the hypothenuse. We use cosine function because we are given in terms of adjacent and hypothenuse. The ratio of cosine function is
cos x = a/h
where x is the angle
Solving for h,
h = a/(cos x) = 21/(cos 30) = 24.25 ft
