Answer:
was this supposed to be funny lol
Step-by-step explanation:
The standard form of a quadratic equation is: ax²+bx+c=0, and it is represented with a polynomial of degree 2, that's why it is also called "Equation of degree 2".
1. So, if 3 and 8 are zeros of the quadratic function, then they are factors of it. Therefore, you have:
(x+3)(x+8)=0
2. When you write it in the standard form, you have:
x²+11x+24=0
a=1
b=11
c=24
Join the center of the hexagon with the 2 base angles.
An equilateral triangle, with side length x, is formed.
(remark: a regular hexagon is made up of 6 equilateral triangles with equal length)
The height
forms 2 congruent right triangles with :
hypotenuse= x, side_1=x/2, and side_2=
.
From the pythagorean theorem we have:
thus, x=4.
The area of the triangle is 1/2 * 4 *
=6.93 (mm squared)
The area of the hexagon is 6* the area of the triangle = 42 (mm squared)
Answer: a. 42 (mm squared)
Answer:
1. The two numbers are 4 and 8.
Step-by-step explanation:
1) variables: x and y
2) x + y = 12, y - x = 4
3) graph using desmos or another graphing calculator
4) the solution is x = 4, y = 8, or 4 and 8. This means that 4 and 8 can be added to equal 12, and the difference between them is 4.
