10x-61/12 is the difference of (7x-) - (-3x +
).
An expression is combination of variables, numbers and operators.
The given expression is (7x-) - (-3x +
)
7x-+3x-
7x-20/3+3x-19/4
Add the variable terms and constant terms.
10x-20/3-19/4
The LCM of 3 and 4 is 12/
10x-4-57/12
10x-61/12
Hence, 10x-61/12 is the difference of (7x-) - (-3x +
).

The length of is given by the relationship between the similar triangles
ΔABD and ΔBDC.
= <u>80</u>
Reasons:
The given parameters are;
The altitude of triangle ΔABD =
The hypotenuse of formed right triangle =
The length of AD = 8
Length of BD = 24
Whereby ΔABD is a right triangle
We have;
ΔABD is similar to ΔBDC
Therefore, by similar triangle proportional sides relationship, we have;
Which gives;
=
Therefore;
Which gives;
