We are given a polynomial representing the area of a barnyard that is <span> 4x2 + 8x - 21. A rectangle's area is equal to length multiplied by the width which means we can use factoring.
</span><span> 4x2 + 8x - 21
(2x - 3 ) (2x + 7)
we can countercheck this to verify the polynomial.
In this case, the dimensions are </span> 2x - 3 and 2x + 7.
Answer:
complementary, x=60
Step-by-step explanation:
complementary angles add up to 90 degrees.
90= x + x- 30
2x= 120
x= 60

Answer:
$48.0
Step-by-step explanation:
Given data
Total cost of DVDs= $24.99+ $19.99
=$44.98
Let us compute the amount of the tax 6.75%
= 6.75/100* 44.98
=0.0675* 44.98
=$3.03615
The total cost including the tax is
=44.98+3.03615
=$48.0
You conjugate verbs with the pronoun 'on' the same way you conjugate verbs with pronouns 'il/elle'. "On" means "one", qs in "One can do x or y."
