<span>In two similar triangles, like the one we see above, the ratio of their areas is the square of the ratio of their sides.
Based on the graph, we see that BD is 3 times larger than BA. This means that the area of DBE will be 3</span>² times larger, or 9 times larger, than the area of ABC.
Area of ABC = 3 square units
Area of DBE = 3 * 9 = 27 square units
Answer is A.
Direct variation is y = kx where y would be the value of the number and x would be its position in the sequence, k is a constant
so for consecutive values y/x would be a constant k
In this case its not true becuse for example 3/1 = 3 and 6/3 = 2
so there is no direct variation here.
Answer:
Step-by-step explanation:
Recognize that the (1/2) in 4n=1/2(2n-12) is a coefficient, the coefficient of the (2n - 12) term.
Thus, multiply both sides of this equation 4n=1/2(2n-12) by 2, to obtain:
8n = 2n - 12
Combining like terms, we get 6n = -12, so that n = -2.
Multiplying both sides of the equation by a constant does not in any way affect your ability to find a solution and does not change the solution.
