Adina has a rectangular garden that measures 9 m wide by 13 m long. She wants to increase the area to 192 m^2 by increasing the width and length by the same amount. What will be the width (shorter dimension) of the new garden?Question 4 options:
a) 14 m wide
b) 13 m wide
c) 12 m wide
d) 11 m wide
Answers
192=(9+x)(13+x)
solve
expand
192=117+22x+x^2
minus 192 both sides
0=x^2+22x-75
factor
0=(x-3)(x+25)
set to zero
x-3=0
x=3
x+25=0
x=-25
not possible since that gives negative legnths and widhs
increased by 3
shorter is 9
9+3=12
C is ansre

The hexagon is split equally, making all the triangles there equilateral, and their angles equal all 60 degrees. That automatically makes angle one and three 60 degrees. For angle two, there is a line, splitting the triangle in half. There are two ways to consider this:
1. Think about the 30°, 60°, 90° special triangles.
or
2. divide 60° by 2, and having 30° in return.

Answer:
5x^2 - 11x = 1
This is now in standard form, where a = 5, b = -11, and c = 1.
Step-by-step explanation:
To rewrite the equation 11x - 5x^2 + 7 = 6 in standard form, we need to rearrange the terms so that the polynomial is in descending order of degree, with no missing terms. The standard form of a quadratic equation is ax^2 + bx + c = 0, where a, b, and c are constants.
So, let's start by moving the constant term to the right-hand side of the equation:
11x - 5x^2 = 6 - 7
11x - 5x^2 = -1
Next, we can multiply both sides of the equation by -1 to make the coefficient of the x^2 term positive:
5x^2 - 11x = 1
This is now in standard form, where a = 5, b = -11, and c = 1.
