Answer:
24 cm
Step-by-step explanation:
8^2 + b^2 = 10^2
64 + b^2 = 10
b^2 = -54
b = 6
10 + 8 + 6 = 24
x= 8 , -3
<h3>What is Quadratic Equation?</h3>
Given:
x² - 5x -24 =0
x² - 8x + 3x -24=0
x(x-8) + 3(x- 8)=0
(x-8)(x+3)=0
x= 8 , -3

q = Sally plays basketball
Required
Determine the contrapositive
For a statement
![p\ -> q](https://tex.z-dn.net/?f=p%5C%20%20-%3E%20q)
<em>Meaning; If p then q</em>
The contrapositive is:
![\¬q -> \¬p](https://tex.z-dn.net/?f=%5C%C2%ACq%20-%3E%20%5C%C2%ACp)
<em>Meaning: If not q, then not p</em>
<em />
Hence;
Option C answers the question
Answer:
x = -7/2 multiplicity 2.
Step-by-step explanation:
4x^2 + 28x + 49 = 0
(2x + 7)(2x + 7) = 0
This is a perfect square.
2x + 7 = 0, so:
x = -7/2 multiplicity 2.
