We want to multiply the monomial by the monomial .
Remember that to multiply monomials we need to use the laws of exponents; in this case, the law for multiplying powers with the same base. The rule says that, when you multiply powers of the same base, you just need to add the exponents: , . Also, is worth pointing out that the exponent of a variable with no exponent is 1: .
Remember that we also need to multiply their coefficients , which are the numbers that multiply the variables; again, variables with no numbers have a coefficient of 1, so . Multiply coefficients is easy, you just need to multiply them as you usually do with everyday numbers.
Let's apply all of that to our multiplication:
We can conclude that 2x times x squared is 2x cubed.
Answer:
Answer:
-2l^2+50l-300 ≥ 0
l(50 − 2l) ≥ 300
(l − 15)(l − 10) ≤ 0
Step-by-step explanation:
Explanation:
Area of the kennel: l(50 − 2l)
Minimum enclosed area required: 300 square feet
The situation is represented by the non-strict inequality l(50 − 2l) ≥ 300.
Solving the inequality, gives several equivalent statements:
50l − 2l2 ≥ 300
-2l2 + 50l − 300 ≥ 0
-2(l2 − 25l + 150) ≥ 0
-2(l − 15)(l − 10) ≥ 0
(l − 15)(l − 10) ≤ 0
