Why is it not reasonable to have a linear trinomial with only one type of letter?

Rus_ich [418]

Because you can just simplify to have 1-2 terms only. Eg:
13+2y+4y (this is a trinomial as it has 3 terms) can be simplified to just give 13+6y

Answer:

Solution given:

AD=1.8

AC=3.0

we have

∆ADC is a right angled triangle

Cos A=b/h

<A=cos-¹ (1.8/3)

<A=53.13°

again

∆ABC is a right angled triangle

Tan A=p/b=BC/AC

Tan 53.13×3=BC

BC=4

NOW

Area of triangle =½(AC*BC)=½(4×3)=6 square units is a required area.

1/4 ÷ 2/3 show,step please

kicyunya [14]

$\frac{1}{4}$ ÷ $\frac{2}{3}$ is the equation

When dividing fractions, you "flip-flop" and multiply

So what that means is that you flip the second fraction and multiply

So $\frac{2}{3}$ is now $\frac{3}{2}$

Now the equation is $\frac{1}{4}$ × $\frac{3}{2}$ which equals $\frac{3}{8}$

Your answer is $\frac{3}{8}$

The formula f 5280m can be used to convert a measurement of f feet to an equivalent measurement of m miles. If an airplane flies

konstantin123 [22]

Just to help you, that formula is saying that 1 mile is equivalent to 5280 feet, i.e. the number of feet is equal to 5280 * number of miles.

So, you know the number of feet = 21,120 and have to convert that into the equivalent number of miles:

f = 5280m => m = f / 5280

m = 21,120 / 5280 = 4 miles

Answer: 4 miles
