$\bf cos(x)-4=sin(x)-4\implies cos(x)=sin(x)\implies \cfrac{cos(x)}{sin(x)}=0
\\\\\\
cot(x)=0\implies \measuredangle x=cot^{-1}(0)\implies \measuredangle x=\frac{\pi }{2}~~,~~\frac{3\pi }{2}$

a rectangular plot of land has the length of 4/7 mile and a width of 3/8 mile. what is the area of this plot?

Tomtit [17]

Answer:

3/14 of a mile

Step-by-step explanation:

It is asking for area. The area of a rectangle is base times height

A = bh

the length can be either the base or the height. It won't matter for this question. Same goes for the width. Lets use 4/7 as the base, and 3/8 as the height.

A = (4/7)(3/8)

*When multiplying fractions, multiply the numerators together, and multiply the denominators together, then simplify the resulting fraction.

A = (4/7)(3/8) becomes

A = 12/56 which reduces to

A = 3/14 (both 12 and 56 are divisible by 4)
