Answer:
Step-by-step explanation:
<u>Entire area is the sum of areas of sections:</u>
- A = 1/2 + 1/2 + 1 + 1/2 + 1/2 =
- 1+ 4*1/2 =
- 1 + 2 =
- 3 sq. units
Answer: 51 %
Step-by-step explanation:
3.5 * 5 = 17.5
17.5 = x/100 * 34
17.5 = 34x/100
17.5 * 100 = 34x
1750 = 34x
x = 1750/34
x = 51.47
rounded to 51%
The solution to the equation x(x+4) = 6 is x = -2 + √10 or x = -2 - √10 after solving with the quadratic formula.
<h3>What is a quadratic equation?</h3>
Any equation of the form where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
We have an equation:
x(x + 4) = 6
By distributive property:
x² + 4x = 6
x² + 4x - 6 = 0
a = 1, b = 4, c = -6
Plugging all the values in the formula:
After calculating:
Thus, the solution to the equation x(x+4) = 6 is x = -2 + √10 or x = -2 - √10 after solving with the quadratic formula.

To find the original price, you could use a variable to represent the original price in this equation;
Let p represent the original price
.70 × p=11.20
to solve this, we'd isolate the variable (p)
p=11.20 ÷.70
p=16
The original price was $16
