<h3>Answer: Choice B)
</h3>
===========================
Explanation:
n = first number
n+2 = second number
Consecutive odd integers are odd numbers that follow one after another. Eg: {3, 5, 7, 9}
Note how I add 2 each time to get the next number. So that explains the "n+2"
Add up n and n+2, then set that sum equal to or larger than 84 like so
We could simplify or solve for n, but I'll stop here since this is what answer choice B is saying.
side note: "at least" means "that value or more". So if I said "at least 10", then I mean "10 or more".
Answer:
(1) 10x + 40
Step-by-step explanation:
5(2x+8)
= 5×2x + 5×8
= <u>10x + 40 (Ans)</u>
Answer: B
Begin by simplifying the given equation, so it's rearranged into standard form. Move all the terms onto one side, so they equal 0. This would result with 
-3x-9=0. Quadratic formula is (-b±√(b²-4ac))/(2a). Standard form follow this variable format: 
+bx+c. Use the numbers that correspond with each variable to substitute them into the quadratic formula. This would be
(-(-3)±√(-3²-4(4)(-9)/2(4).
Answer:
Step-by-step explanation:
Given
Jar contains 15 Green and
15 Purple marbles
Total marble
Probability of Picking a Purple marble is
Therefore probability of picking a marble is 
(a) 151 degrees (supplementary angles add to 180’)
(b) 48 degrees (complementary angles add to 90’)
