B........................
Perimeter = 2(l+w) or 2(length+width)
So far you have the width, which is 19feet. Since you have two sides of the rectangle which are 19 feet, add 19+19=38
Subtract 62-38 to get 24.
You now have the length of both of the sides combined. So you need to divide 24/2 = 12
The length of the rectangle = 12ft.
Answer:
B and D
Step-by-step explanation:
Answer:
4m
Step-by-step explanation:
Answer: first option 3, - 7
Justification:
1) Given expression:9x² - 5x - 7
2) Each monomial is a term.
The monomials are each combination of numbers and letters (coefficient, letters and exponents) separated of other monomials (terms) with a + or - operator.
3) Therefore, there are 3 terms which are:
9x²,
-5x, and
-7.
The polynomials with 3 terms are called monomials.
4) The monomial (term) withoud letter is the constant. In this case that is -7.
