3.5x=42

x represents the length, since the formula to find area of a rectangle is width times length.

Answer:

A=3.5\cdot{x}

Step-by-step explanation:

Area is defined as width mutiplied by length. We assume the desk is rectangle. The following equation represents the area of the desk:

A=3.5\cdot{x}

A is the area and x is the length. We can therefore determine the length:

x=A/3.5=42/3.5=12

The length is 12 ft

What is the probability of tossing two heads
vodka [1.7K]

Hello!

Each time, there will be a 1/2 chance of tossing a head. Therefore, we multiply our two probabilities.

1/2(1/2)=1/4

Therefore, we have a 1/4 or 25% chance of tossing two heads in a row.

I hope this helps!

Some things to know
point slope form: for a line passing through (x1,y1) and the slope is m
y-y1=m(x-x1)

horizontal lines are y=constant

y=mx+b, m is slope and b is y intercept

the slope of the line that passes through the points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)

1.
y-2=2/3(x-(-3))
y-2=2/3(x+3)

2.
find slope
(-2-3)/(6-(-4))=(-5)/(6+4)=-5/10=-1/2
a point isi (-4,3) and slope is -1/2
y-3=-1/2(x-(-4))
y-3=-1/2(x+4)

3.
yintercept of 2 means (0,2) is a point
find slope between (0,2) and (12,4)
(4-2)/(12-0)=2/12=1/6
a point is (12,4)
y-4=1/6(x-12)

4.
horizontal is y=something
(x,y)
(-2,-9)
we have y=-9
y=-9 is the equaiton

5.
y=-2x+3
y=mx+b
-2 is slope
a point is (-6,2)
y-2=-2(x-(-6))
y-2=-2(x+6)
