Answer:
<em>Riko is wrong because she uses the wrong formula.</em>
Step-by-step explanation:
Given the coordinate points (-2, -3) and (2, -5)
We are to find the distance between the two points
Using the formula:
D = √(x2-x1)²+(y2-y1)²
From the coordinates x1 = -2, y1 = -3, x2 = 2 and y2 = -5
Substitute
D = √(2-(-2))²+(-5-(-3))²
D= √(4)²+(-2)²
D = √16 + 4
D = √20
D = √4*√5
D = 2√5
<em>This shows that Riko is wrong because she uses the wrong formula.</em>
Answer:
The Area of the shaded region = (Area of the largest circle) – (Area of the circle with radius 3) – (Area of the circle with radius 2). Whatever is left over is the shaded region. The diameter of the largest circle is 10, so its radius is 5 and thus its area is 25π. SO do this in that problem and you will get the answer.

Answer:
<h2>x = 5/2 , x = - 4/3</h2>
Step-by-step explanation:
6x² - 7x - 20 = 0
Using method of factorization
Rewrite - 7x as a difference
That's
6x² + 8x - 15x - 20 = 0
Factor the expression
That's
2x( 3x + 4) - 5( 3x + 4) = 0
Which is
(2x - 5) (3x + 4) = 0
2x - 5 = 0
2x = 5
Divide both sides by 2
x = 5/2
3x + 4 = 0
3x = - 4
Divide both sides by 3
x = -4/3
Hope this helps you
