3,4 and 5 are pythagoras triplet
then you check 18 is 6*3 and 24 is 6*4 so the missed side length will be 6*5=30
so choice d. is right sure
hope helped
Answer:
- 2x - 7y
Step-by-step explanation:
Given
- (4x + y) + 2(x - 3y)
Distribute both parenthesis, noting that the first is distributed by - 1
= - 4x - y + 2x - 6y ← collect like terms
= (- 4x + 2x) + (- y - 6y )
= - 2x + (- 7y) = - 2x - 7y
Approximate the real zeros of f(x) = x2 + 3x + 1 to the nearest tenth
<u>C. 2.6,-0.4</u>
<u />
sin45=5/x so x is 5/(sin45)
y is 5/(tan45)
question 5 then you just go x= (9sqrt(2)/2)/sin45
i don’t have a calculator rn so just plug it into it
Answer:
8,8,8,7
Step-by-step explanation:
5,6,7,8,8,10,12
8 is the median since its the number in the middle
8 is the mode since it is the repeated number
7 is the range since 12-5 is 7
all the numbers added and divided by the number of numbers is the mean
(5+6+7+8+8+10+12)/7=8
