Squares are:
1. Equal on all 4 sides
2. All Have the same angle measure of 90 degrees
Answer:
23
Step-by-step explanation:
First subtract 7 and 4.
7-4=3
6-3=3
________
7+3+6+3+4
7+3=10
10+6=16
16+3=19
19+4=23
(Ignore the 3 inside the shape)
The value of expanding (2x -3)^4 is 16x^4 + 96x^3 +216x^2 -216x + 81
<h3>How to expand the expression?</h3>
The expression is given as:
(2x -3)^4
Using the binomial expansion, we have:

Evaluate the combination factors.
So, we have:

Evaluate the exponents and the products

Hence, the value of expanding (2x -3)^4 is 16x^4 + 96x^3 +216x^2 -216x + 81

An equation for the sentence would be g + 7 = 12, where g is the unknown number of gallons.
Hi there!
Since one of the angles in this set of 2 lines is a right angle, we know that every other angle is a right angle because vertical angles are congruent and that because each line has a total of 180 degrees.
Thus, Angle NDA and RDY are both 90 degrees and add up to 180 degrees.
Since the two angles add up to 180, they are supplementary angles.
Also, we should notice that those two angles are across each other. Thus, they are also vertical angles.
Your answers are choices B and C.
Have an awesome day! :)
