Answer:
414 yd²
Step-by-step explanation:
The area can be resolved into three rectangles. The figure's area is the sum of the areas of those.
Figure area = sum of LW
= (23 yd)(15 yd) +(3 yd)(3 yd) +(5 yd)(12 yd)
= 345 yd² +9 yd² +60 yd²
= 414 yd²
<h3>Answer: 414 square yards</h3>
========================================================
Explanation:
Surround the entire figure in a bounding rectangle as shown below.
This surrounding rectangle is 23 by 27. It's total area is 23*27 = 621 square yards.
For a moment, let's ignore the 3x3 section marked in the dashed lines. The empty space in the bottom left corner is 15+3 = 18 by 9+3 = 12. Its area is 18*12 = 216 square yards. Accounting for the dash line 3x3 section means we subtract 9 from the 216 to get 216-9 = 207. The empty space takes up 207 square yards.
So the purple region must take up 621-207 = 414 square yards

Answer:
Step-by-step explanation:
There are 3 ways to find the other x intercept.
1) Polynomial Long Division.
Divide x^2 - 3x + 2 by the binomial x - 2, because by the Factor Theorem if a is a root of a polynomial then x - a is a factor of said polynomial.
2) Just solving for x when y = 0, by using the quadratic formula.
.
So the other x - intercept is at (1, 0)
3) Using Vietta's Theorem regarding the solutions of a quadratic
Namely, the sum of the solutions of a quadratic equation is equal to the quotient between the negative coefficient of the linear term divided by the coefficient of the quadratic term.
And the product between the solutions of a quadratic equation is just the quotient between the constant term and the coefficient of the quadratic term.
These relations between the solutions give us a brief idea of what the solutions should be like.
