Hint: "4x 2 - 25 = 0" is nearly meaningless. You want 4x^2 - 25 = 0.
Note that both 4x^2 and 25 are perfect squares, so this is the difference of two squares, and is equal to (2x-5)(2x+5)= 0.
Answer:
a parallelogram is a rectangle so the sides are 3cm and the other two are 7cm
Step-by-step explanation:
how to calculate the area is u multiply 7 by three and there is your answer
Answer:
Well, I am not sure which one is equivalent to another, but I have some information that should help you find your answer.
Step-by-step explanation:
The simplified expression to x2 − x − 6 x2 + 2x − 15 would be equal to −5 x 2 + x − 15.
The simplified expression to x + 3 x + 5 would be equal to 4x + 5.
The simplified expression to x + 2x + 5 would be equal to 3x + 5.
The simplified expression x + 3 x − 3 would be equal to 4x − 3.
The last simplified expression to x + 2 x − 3 would be equal to 3x − 3.
Hope this helps, I am really sorry if I didn't answer your question properly, or the way you asked!
Answer:
1^x-2
Step-by-step explanation:
First you put log(10)^x into the calculator, the product is 1^x. Then you subtract that by log(10)^3 which you you get 1^x-1 then you subtract that answer by 1 to get 1^x-2.
