2 answers:
Answer:
D
Step-by-step explanation:
Start by subtracting 64 from both sides:
Factor this by taking roots. Divide both sides by 25 first:
We "undo" a square by taking the square roots of both sides. Taking the square root leaves the possibilities of both the positive and negative roots of 9. Therefore, the solutions to this are

Answer:
A coordinate grid that shows a point located halfway between 3 and 4 units to the right and 1 unit down from the origin
Step-by-step explanation:
In a coordinate grid, the y axis is plotted on the vertical axis and the x axis is plotted on the horizontal axis. A is plotted on a coordinate grid at () i.e (
). Above the origin is the positive y axis, below the origin is the negative y axis, right of the origin is the positive x axis and left of the origin is the negative x axis.
To plot A on the coordinate axis we need to locate on the x axis and -1 on the y axis.
is halfway between 3 and 4, since the x coordinate is positive it is located to the right between 3 and 4 and since the y coordinate is negative it is located 1 unit down from the origin.
Answer:
X= 17
Step-by-step explanation:
In the picture above , you see that
BAE =~ DAE
So , just substitute the equation of each other and solve for x.
That's it.
