Answer:
Part 1) Is a cubic expression
Part 2) The quadratic expression is 12x² + 8x − 1
Step-by-step explanation:
Part 1) Classify the expression: 5x³ + 2x − 3
we know that
Polynomials can be classified two different ways - by the number of terms and by their degree.
so
a) <u>By the number of terms</u> is a trinomial, because has three terms
b) <u>By their degree</u> The degree of the polynomial is found by looking at the term with the highest exponent on its variable
The highest exponent is 3 so this is a 3rd degree trinomial
therefore
Is a cubic expression
Part 2) Choose the expression that represents a quadratic expression
we know that
If the expression is a quadratic equation , then the highest exponent of the variable is 2
therefore
The quadratic expression is 12x² + 8x − 1
To know which fraction is greater than another is to first look at the denominator
<u>example</u>
if u look at the denominator the one with the highest denominator is the smallest and then you look at the numerator to imagine if its closer to the denominator or farther away from the denominator.
80 kilometer = 80,000
80 kilomets converts to 80,000 meters
Answer:
x= 4/5a
Step-by-step explanation:
5=5/ax+1
Step 1: Multiply both sides by a.
5a=a+5x
Step 2: Flip the equation.
a+5x=5a
Step 3: Add -a to both sides.
a+5x+−a=5a+−a
5x=4a
Step 4: Divide both sides by 5.
5x/5=4a/5
x= 4/5a
Hope this helps!
