Step-by-step explanation:

You know the lengths of two sides and the angle between them, so use the Law of Cosines to find the third side.

x^2 = 10.5^2+ 5.4^2 -2(10.5)(5.4)cos20°

x ≈ 5.73 units

What conversion factor would you use to solve thikproblem?

ira [324]

Conversion factor is the term that is to be multiplied to a variable when converting between units. The conversion factor is: $2.20lbs /kg$

Given that:

$54kg \to x\ lbs$

From standard unit of conversion:

$1kg = 2.20lbs$

So, we have:

$54kg \to x\ lbs$

$1kg = 2.20lbs$

Cross multiply

$54kg \times 2.20lbs = xlbs \times 1kg$

Divide both sides by 1kg

$54kg \times 2.20lbs /kg= xlbs$

Rewrite as:

$x = 54kg \times 2.20lbs /kg$

Hence, the conversion factor is: $2.20lbs /kg$

Which expression is equivalent to 16x +42y?

V125BC [204]

Find the Greatest Common Factor (GCF)

GCF = 2

Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

2(16x/2 + 42y/2)

Simplify each term in parenthesis
