What is the answer to 6(x+4)=30
DanielleElmas [232]

Start by distributing the 6 through the parenthses on the left side.

So we have 6x + 24 = 30.

Solving from here, I would subtract 24 from both sides to get 6x = 6.

Finally, dividing both sides of the equation by 6, we have x = 1.

A rectangle has vertices a(1,2), B(1,7), c(4,7), d(4,2). what is the perimiter of the rectangle
aliina [53]

Answer:

16

Step-by-step explanation:

You see, if you were to plot these points, (1, 2) and (1, 7) would be 5 points away from each other. If you were to plot the points (4, 2) and (4, 7) those points would also be 5 points away from each other. Now, (1, 2) and (4, 2) are 3 points apart as well as (1, 7) and (4, 7). Therefore, 5 + 5 = 10, 3 + 3 = 6, and finally, 10 + 6 = 16!

Divide 30 in the ratio of 2 : 4
cricket20 [7]
60 because 2:4 is 1/2, and when you divide by a fraction, you multiply by the reciprocal (2/1 instead of 1/2) which would be 60 in this case.
