This would be easiest to do by completing the square.
x^2+10x-2=0
x^2+10x=2
x^2+10x+25=27
(x+5)^2=27
x+5=±√27
x=-5±√27
(x+5+√27)(x+5-√27)
1. 2(10)
4(20)
6(30)
I only know the answer to number 1 sorry. :/
Answer:
Step-by-step explanation:
we know that
The probability that a point chosen randomly inside the rectangle is in the square is equal to divide the area of the square by the area of rectangle
Let
x-----> the area of square
y----> the area of rectangle
P -----> the probability
<em>Find the area of square (x)</em>
<em>Find the area of rectangle (y)</em>
Find the probability P
Answer: AB = 30cm, BD = 16cm, CD = 30 cm, AC = 16 cm
