Answer: 6+4x=26, 4x=20
Step-by-step explanation: 6+4x=20 is the initial equation but completely multiplied by two, so you can know without solving that it is equivalent.
If you solve the equation, 2x+3=13 (subtract 3 from both sides)
2x=10 (divide both sides by 2)
x equals 5.
if you plug in 5 as x to 4x=20, you get 20=20, which is a true statement, so this choice is also correct. You could also solve to prove x equals 5 in this equation as well. Divide 20 by 4 and you get x=5.
Answer: 80
Step-by-step explanation:
100+80 =180
Which of the following is a geometric sequence? A. 1, 1, 2, 3, 5, ... B. 2, 4, 6, 8, ... C. 7, 4, 1, -2, ... D. 1, ½, ¼, ⅛
Nonamiya [84]
A geometric sequence is when each term is found by multiplying the previous term by a constant. in this case, the answer is D because each term is being multiplied by 0.5, hope this helps!
Using mathematical operations we can conclude that the area of the given figure is 40 units².

What are mathematical operations?</h3>
- An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value.
- The operation's arity is determined by the number of operands.
- A mathematical action is called an operation.
- Mathematical operations include addition, subtraction, multiplication, division, and finding the root.
So, the area of the figure:
Where x = 4, so the expression will become:
Now, do the mathematical operations to get the area of the figure as follows:
- x² + x² + x + x
- 4² + 4² + 4 + 4
- 16 + 16 + 8
- 40
'
Therefore, using mathematical operations we can conclude that the area of the given figure is 40 units².
