Step-by-step explanation:
Length = x-3
width = x+8
Area of the rectangle = 60 inch²
(x-3)(x+8)=60
x²+8x-3x-24=60
x²+5x-24=60
x²+5x-84=0
x²+12x-7x-84=0
x(x+12) - 7(x+ 12) =0
(x+12)(x-7)= 0
x= -12 or, x= 7
Measure of sides of rectangle can never be negative.
Answers:
Therefore,
x=7
Dimensions
length =7-3
=4 inches
width = 7+8
=15 inches
A+b=180° because they are a linear pair
(2x+10)+(3x+20)=180
5x+30=180
5x=150
x=30
a=c because they are vertical angles
2(30)+10= C
60+10=C
70=C
Answer:
6. - 4+2=-2, -2+2=0, -1+2=1 therefore the lower the initial value the higher the result will be. This is because of the fact that x is a negative.
7. After 5 iterations of the equation -2[x-2]+4 it ended up looping at 1.6 and 3.2, they just kept repeating each other.
8. This loop is never ending it took me 13 iterations to see that it will works it will result in 2.24 again just as the 3 iteration.
9. My function was 4(x)-x^2 with an initial value of 2, after ten times I got a value of 3.51 it looped over and over.
11. I do not notice any type of relationship.
If anyone finds number 10 let me know, I'm stuck.
