Is it possible to construct a triangle with side lengths of 11 cm, 15 cm, and 21 cm? Why or why not?

There is only one requirement for three sides in order to be considered possible in constructing a triangle. That requirement is
The sum of any of the two sides must be greater than the third side

11 + 15 = 26 > 21
11+ 21 = 33 > 15
15 + 21 = 16 > 11

Since all of the combination fulfill the requirement, yes we could create the triangle with those sides.

Since all of the sums are greater than the third side, it is possible to make a triangle with these three sides.

Help with part A and part B

Vitek1552 [10]

A. You can use y=mx+b to find the rate of change of a bushel corn in the current year. The rate of change would be y=8x.

B. One bushel is worth 8$ (24/3 = 8) in the current year, and in the previous year one bushel was worth 7$ (21/3= 7). Therefore there was a 1$ raise from the previous year to the current year.

Given:

The given expression is $\frac{4 d+28}{12 d+96} \cdot \frac{d^{2}+14 d+48}{d^{2}+9 d+14}$

We need to multiply the terms.

Multiplication of the terms:

Before multiplying the terms, first we shall find the factors of the quadratic equations.

Thus, we have;

$\frac{4 d+28}{12 d+96} \cdot \frac{(d+6)(d+8)}{(d+2)(d+7)}$

Factor out the common terms, we get;

$\frac{4 (d+7)}{12 (d+8)} \cdot \frac{(d+6)(d+8)}{(d+2)(d+7)}$

Let us cancel the common terms from the above expression.

Thus, we have;

$\frac{4 }{12 } \cdot \frac{(d+6)}{(d+2)}$

Simplifying, the term, we get;

$\frac{1}{3 } \cdot \frac{(d+6)}{(d+2)}$

Now, we shall multiply the terms.

Hence, multiplying the terms, we get;

$\frac{(d+6)}{3(d+2)}$

Thus, the multiplied value of the given expression is $\frac{(d+6)}{3(d+2)}$

What is the fraction of 0.344

Genrish500 [490]

Hello!

$\bf Answer:$

$\boxed{ \bf 0.334~=~344/100~or~43/125}$ as a fraction.

0.344 = 0.344/1

The 4 is in the thousandths place. Multiply both the numerator and the denominator by 1000.

0.344 × 1000 = 344

1 × 1000 = 1000

This gives us: 344/1000

It's fraction form can be reduced. Simply divide both the numerator and the denominator by 8:

344 ÷ 8 = 43

1000 ÷ 8 = 125
