You have to plug in the values into the equation.
Since a=6, all the a's in the equation would be replaced by 6 and same goes for the b.
^ means exponent btw
= -[2(6)^2 -6- (5(6)^2-3(3)) -4(6)^2 +2(3)]
Calculate/ simplify
= -[2(36)-6 - (5(36) -9)-4(36)+6]
Multiply all the things in parenthesis
= -[72-6-(171)-144+6]
Add/subtract
= -[-243]
Negative times negative becomes positive therefore, the answer becomes 243
Answer: No. Jamies reasoning doesn't make any sense.
Counter example :- Isha decides to go on walk on every 4th day and go for gym on every 2nd day in a month.
Then Isha will do both the things on same day = LCM (4,2)
Now, LCM of 4 and 2 = 4
Therefore, Isha will do both the things on 4th day of the month .
Step-by-step explanation:
Jamies reasoning doesn't make any sense.
Because the LCM of 3 and 6 = 6 not 18[since 6=3×2]
LCM is the least common multiple number of two or more numbers.
Answer: you spent 250 hours during your cleanup.
you spent 150 hours painting
Step-by-step explanation:
Let x represent the number of hours that you spent during your cleanup.
Let y represent the number of hours that you spent painting.
you earn $8 an hour cleaning up and $12 an hour painting last summer and you earned $3800 . it means that
8x + 12y = 3800- - - - - - - - - -- 1
You worked a total of 400 hours. This means that
x + y = 400
Substituting x = 400 - y into equation 1, it becomes
8(400 - y) + 12y = 3800
3200 - 8y + 12y = 3800
- 8y + 12y = 3800 - 3200
4y = 600
y = 600/4 = 150 hours
Substituting y = 150 into x = 400 - y, it becomes
x = 400 - 150
x = 250 hours
Answer:
Cone Volume = (PI * radius^2 * height) / 3
Cone Volume = (PI * 6^2 * 12) / 3
Cone Volume = 452.3893421169 cubic inches

Step-by-step explanation:
You write the inverse of a conditional statement by negating both the hypothesis and the conclusion.
So, the inverse of
is
So, in your case, the inverse of your statement is
If a shape is not a rhombus, then it doesn't have four congruent sides.
