Remark
An altitude is a very special line. It must start from one of the angles and connect with the side opposite that angle. The connection must form a right angle.
It cannot start anywhere else -- certainly not in the middle of a line which would make the altitude of random importance. It could not be accurately reproduced.
The basic facts she used to help her estimate are (c) 28 + 7 and (d) 30 + 5
<h3>What are estimates?</h3>
Estimates are approximated calculations that are used in place of an actual calculation
The expression is given as:
28 + 7
When the numbers are approximated to the nearest 5, we have:
30 + 5
Hence, the basic facts she used to help her estimate are (c) 28 + 7 and (d) 30 + 5

133
Solution
x2 -3xy
=(-7)2- 3x(-7) x 4
=49 + 21 x 4
=49 + 84
=133
Note: I put 2 instead of the “mini 2” or squared cuz I cant copy and paste it lol
So, $175 is the total of 10 hours of his work. We have to divide the 175 to 10 so that we can get his hourly wage. 175 divided by 10 is 17.5. Multiply the 17.5 to 8 hours, its $140
