Answer:
18√2
Step-by-step explanation:
The area of the smaller triangle is 1/2 that of the larger one. Since the triangles are similar, the dimensions of the smaller triangle are √(1/2) those of the larger one.
36 · √(1/2) = 36 · (√2)/2 = 18√2 . . . . length of line dividing the triangle
Domain: (-infinity, infinity)
Range: (-infinity, infinity)
25 = 5.2 + 8 + x
5.2 + 8 = 13.2
25 = 13.2 + x
25 - 13.2 = 11.8
11.8 = x
The unknown side is 11.8 ft.
X^2 = 36...take the square root of both sides, eliminating the ^2
x = (+-) square root 36
x = (+-) 6
so x = -6 and x = 6
answer is : its the one where a dot is shown on 6 and another dot on -6, and are labeled as p and q ,respectfully
Answer:
a. 10x + 4; the answer is a polynomial
Step-by-step explanation:
The perimeter of a rectangle is the sum of the lengths of the 4 sides.
The closure property is that if you add polynomials, the sum is a polynomial.
A rectangle has two congruent lengths and two congruent widths.
Since the length of the rectangle is 3x + 5, there is another length of 3x + 5. The width is 2x - 3, so there is a second width of also 2x - 3.
Let's add the 4 sides together:
3x + 5 + 3x + 5 + 2x - 3 + 2x - 3 =
= 3x + 3x + 2x + 2x + 5 + 5 - 3 - 3
= 10x + 4
The perimeter is 10x + 4. Each side length is a polynomial, and the sum of the all the side length is also a polynomial. This shows there is closure for the addition of polynomials.
