Answer:
4)2.4
Step-by-step explanation:
-1.5 ( -3.6 + 2 )
To solve this problem, we apply PEMDAS.
This is the order of operation for mathematical problems.
P Parentheses
E Exponent
M Multiplication
D Division
A Addition
S Subtraction
-1.5 ( -3.6 + 2 )
Do the problem in the parentheses first,
= -1.5 x (-1.6)
= 2.4
The distributive properties of addition and subtraction can be used to rewrite expressions for a variety of purposes. In each case, you are distributing the outside multiplier to each number in the parentheses, so that multiplication occurs with each number before addition or subtraction occurs.
CD is the perpendicular bisector of another line AB which can be proven below.
<h3>What is perpendicular bisector?</h3>
Perpendicular bisector is a line that divides another line into two equal halves in such a way that it creates an angel of 90°.
To proof that CD is the perpendicular bisector of another line AB the following is carried out;
- Draw a line segment AB with length of about 5 cm.
- With any radius greater than 2.5 cm, and compass fixed at A, draw 2 arcs, one above and one below AB.
- With the same radius, compass at B, cut the 2 arcs drawn in step 2.
- The line joining these two arcs is the perpendicular bisector of AB.
