Answer:
A, B and D
Step-by-step explanation:
Following are steps in practical problem solving:
=> Assign an identifying variable to the quantity to be found.
=> Write a sentence stating conditions placed on the quantity.
=> Solve the sentence for the variable.
P(x)=2x^2-4x
q(x)=x-3
(p*q)(x)
(2x^2-4x)(x-3)
2x^3-10x^2+12x
The lateral area consists of 3 triangles of base 6 cm and height 9 cm
Lateral area = 3 * 1/2 * 6 * 9 = 81 cm^2 answer

3: Not really, whole numbers are being used and fractions are honestly not needed in this situation.
4: If that was the case, you most likely did your work wrong. Check back and see if you've made an error in your word problem.

Is it possible you can focus more on the rectangle since the numbers are hard to see? :)
Plot i = 200 seeds
Geminated = 57% of 200 = 0.57 x 200 = 114 seeds
Plot ii = 300 seeds
Geminated = 42% of 300 = 0.42 x 300 = 126 seeds
Total geminated seeds = 114 + 126 = 240
Total seeds = 200 + 300 = 500
Percentage = 240 ÷ 500 x 100 = 48%
