Simply, you subtract the spa area from the deck one.
A = (6x+10)(3x+4)-[(5x+2)(2x+1)]
A = 18x^2+24x+30x+40-(10x^2+5x+4x+2)
A = 18x^2+24x+30x+40-10x^2-5x-4x-2
A = 8x^2 + 45x + 38

Answer:
<h2>5/48</h2>
Step-by-step explanation:
Given
the sample space for box A
green balls = 5
red balls= 7
sample size= 5+7= 12
the sample space for box B
green balls = 3
red balls= 3
yellow balls= 6
sample size= 3+3+6= 12
The probability of drawing a green ball from box A= 5/12
The probability of drawing a green ball from box B= 3/12= 1/4
Therefore the probability of picking a green ball from either of the boxes at random is =
Y · y = y²
when multiplying exponents, you add them together
Solve the equation by substitution method.
To get b-2-3b=4. Then you substitute b into simplest to get, b=-3. Repeat the same process with a to get, a=-5. So your answer would be (-5, -3)
