Answer:
0.6
Step-by-step explanation:
First make them into decimals so.
9.4 - 8.8 = 0.6
The <em><u>correct answer</u></em> is:
The degree of the polynomial is 4 and the maximum number of terms is 9.
Explanation:
Multiplying the terms of each trinomial that have the largest degree, we are multiplying x²(x²); this gives us x⁴. This means the degree of the trinomial, the largest degree of all terms, is 4.
Without multiplying through, we know we will multiply each term of the first trinomial by each term of the second one. This means that, if no terms are like to combine, we could have 3(3) = 9 terms.
Answer:
c = - 2, c = 7
Step-by-step explanation:
Given
c² - 14 = 5c ( subtract 5c from both sides )
c² - 5c - 14 = 0 ← in standard form
To factorise the quadratic
Consider the factors of the constant term (- 14) which sum to give the coefficient of the c- term (- 5)
The factors are - 7 and + 2, since
- 7 × 2 = - 14 and - 7 + 2 = - 5, hence
(c - 7)(c + 2) = 0
Equate each factor to zero and solve for c
c - 7 = 0 ⇒ c = 7
c + 2 = 0 ⇒ c = - 2
Answer:
20%
Step-by-step explanation:
<u><em>Given/To Find:</em></u>
<em>A $52.50 screen door is on</em>
<em>sale for $42. Find the percent</em>
<em>of discount on the door.</em>
<u><em>Solve:</em></u>
<em>Formula: Value 1 - Value 2 ÷ Original Value × 100</em>
<em />
<em>Hence we have:</em>
<em>52.50 - 42 = 10.5</em>
<em>10.5 ÷ 52.50 = 0.20</em>
<em>0.20 × 100</em>
<em>=20%</em>
<em />
<em>Check Answer:</em>
<em>52.50 × 20% = 10.5</em>
<em>52.50 - 10.5 = 42</em>
<em>Hence, the percent of discount on the door is 20%</em>

The circumcenter of a triangle is the point where the perpendicular bisectors of the sides intersect. It is also the center of the circumcircle, the circle that passes through all three vertices of the triangle. This page shows how to construct (draw) the circumcenter of a triangle with compass and straightedge or ruler. This construction assumes you are already familiar with Constructing the Perpendicular Bisector of a Line Segment.
