Answer:
width = 3.5 m
length = 18 m
Step-by-step explanation:
area = length x width
x is the width then length = 2x + 11
x(2x + 11) = 63
2x^2 + 11x - 63 = 0
The formula to solve a quadratic equation of the form ax^2 + bx + c = 0 is equal to x = [-b +/-√(b^2 - 4ac)]/2a
with a = 2
b = 11
c = -63
substitute in the formula
x = [-11 +/- √(11^2 - 4(2)(-63))]2(2)
x = [-11 +/- √(121 + 504)]/4
x = [-11 +/- √625]/4
x = (-11 +/- 25)/4
x1 = (-11 + 25)/4 = 14/4 = 3.5
x2 = (-11 - 25)/4 = -36/4 = -9
since width can't be a negative number, x is 3.5
length = 2x + 11 = 2(3.5) + 11 = 18
(7+11) is 18, (8/2) is 4, 18-4 is 14! If this expression is 6 less than her age, she would be 20!

Answer:
0.24
Step-by-step explanation:
Probability is the ratio of the number of possible outcome to the number of total outcome. The probability that an even will happen or not happen is 1.
Given that the spun has 10 sections 3 red, 3 blue and 4 green, the probability of not getting green
= (3 + 3)/(3 + 3 + 4)
= 6/10
The probability of getting green
= 4/10
Hence the probability of getting not green then green
= 6/10 * 4/10
= 24/100
= 0.24
