2a.
Since BC = 10m and M is the midpoint, we can find CM by : 10÷2 = 5m
So, CM = 5m
2b. Now, you have the base ( 5m) & hypotenuse (13m). Pythagoras' Theorem:

Where c is the hypotenuse, a & b are sides.

b here refers to the height.
2c.
Area of a right-angled triangle =

So,
Answer: A) 6x = 54; x = 9 times older
Step-by-step explanation:
9 x 6 = 54
Answer:
x=6,y=13
Step-by-step explanation:
Eliminate the equal sides of each equation and combine.
x+7=2x+1
Solve x+7=2x+1
x=6
Evaluate yy when x=6
y=13
The solution to the system is the complete set of ordered pairs that are valid solutions.
(6,13)
The result can be shown in multiple forms.
Point Form:
(6,13)
Equation Form:
x=6,y=13
<em>Solve: </em>

Start by isolating the x-variable as much as you can:


Now, if we take the log with base 13 of both sides, then the left hand side will cancel out really easily. This is based on the concept of inverse operations. For example, when we take the square of a square root, we get our initial value. This is because the two operations are inverses of each other, and basically undoes each other.
Logarithms and exponentials are the inverse operations of each other. If we want to extrapolate the power of an exponential, we take the logarithmic function of it, and vice versa.
In this case, we are saying what power of '13' will produce us with 13ˣ, and the only answer will be x itself.

The slope is 0 and the equation of the line is y= -2.
