Yes, it is because a square is a <span>quadrilateral with all the the four sides congruent, but the parralelogram is also a quadrilateral with the two by two sides congruent, that means the square is a parallelogram.</span>
Marvin can fun 52 KM in 6 Hours and 30 Min
First you divide 48 km /6 hours to find out how many km he ran per hour
48 km /6 hours = 8km/h
So you then multiply 8 km/h x 6.5 hours to find out how many km he ran in 6 hours and 30 mins.
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = -4
Hope this helps! :)
Happy New Years!
For this case we have the following equation:
-2y2 + 6y = -2
Rewriting we have:
-2y2 + 6y + 2 = 0
Using the quadratic formula we have:
x = (- b +/- root (b ^ 2 - 4 * a * c)) / (2 * a)
Substituting values:
x = (- (6) +/- root ((6) ^ 2 - 4 * (- 2) * (2))) / (2 * (- 2))
Rewriting:
x = (- 6 +/- root (36 + 16)) / (- 4)
x = (- 6 +/- root (52)) / (- 4)
x = (- 6 +/- root (4 * 13)) / (- 4)
x = (- 6 +/- 2 * root (13)) / (- 4)
x = (- 3 +/- root (13)) / (- 2)
The roots are:
x1 = (- 3 - root (13)) / (- 2)
x2 = (- 3 + root (13)) / (- 2)
Rewriting:
x1 = -0.3
x2 = 3.3
Answer:
–0.3, 3.3
Answer:
3x^2 +8x +3
Step-by-step explanation:
(6x^2 + 8x - 3) - (3x^2 - 6)
Distribute the minus sign
(6x^2 + 8x - 3) - 3x^2 + 6
Combine like terms
3x^2 +8x +3
