what is x and how did you get it i need help pleasee
hi please HELP ME I really need it
Answer:
? = 14
Step-by-step explanation:
let us say that ? = x
7^x * 7^5^4 = 7^34
When you have a power to a power you multiply
7^x * 7^20 = 7^34
when you multiply common bases you add the power. since all the bases aer the same just look at the power
7^34-20 = 7^x
7^14 = 7^x

Answer:
The second option.
Step-by-step explanation:
I did this quiz before, here is an explaination.
You add 0 to 81.3 and it becomes 81.30, then you're able to subtract it from 6.45, you subtract from left to right to find the answer with regrouping!
Using algebra tiles, show a model of 4x + 2.
Answer:
Your Correct answer for this question is the first option.
Step-by-step explanation:
The Four 1 tiles on the first half of 4x+2 represent the 4, and the x represents the variable! Then the question is separated by a plus sign and Two more 1 tiles, which represent 4x+2
Steps to solve:Step 1:
Add all the tiles from the first sector of the question before the +.
(1+1+1+1+x) = 4x
Step 2:
Add the second sector together.
(1+1) = 2
Step 3:
Combine all sectors together.
(4x) + (2) = 4x +2

What is your question? Could you further explain what you are asking?
Weight Lifting A weight lifter puts an
X-pound weight on each side of a bar.
A weight 5 pounds heavier than the first is
then added to both sides. Finally, a weight
5 pounds heavier than the second weight
is added to both sides. The expression
2[x + (x + 5) + (x + 2(5))]models the
total weight lifted. Simplify the expression.
What would the expression be if each added
weight was 10 pounds heavier than the
previous weight?
Answer:
Expression: 6x + 30
Step-by-step explanation:
2[x + (x + 5) + (x + 2(5))]
2[2x + 5 + x + 10]
2(3x + 15)
6x + 30

How do I solve this (trigonometry)
Answer:
3/5
Step-by-step explanation:
the sin of an acute angle in a right triangle is the ratio of the opposite side to the hypotenuse
24/40=3/5
Answer:
sine of Z = 36.87 (36.86989765 to be exact)
Step-by-step explanation:
Remember SOH-CAH-TOA
Sine=OH=opposite/hypotenuse.
You want to find the angle of Z so, theta Z= 24/40 (O/H)
On your calculator, put inverse sine(sin ^-1) of 24/40.
So, sin-1 (24/40)=36.87 degrees.
