Answer:
So the expression in standard form will be 
Step-by-step explanation:
We have given expression 
We have to write this expression in standard form
For writing in standard form first we have to multiply the expression
So after multiplication number 
So the expression in standard form will be
<h3>
Answer: C) 5</h3>
==========================================================
Work Shown:
s = square side length
A = area of square = 9x^2+12x+4
A = s^2
A = (ax+b)^2
A = a^2*x^2 + 2abx + b^2 .... apply the FOIL rule
A = 9x^2 + 12x + 4
Equating corresponding terms, we see that,
- a^2*x^2 = 9x^2 which shows that a^2 = 9 and that solves to a = 3, assuming 'a' is positive.
- 2abx = 12x leads to 2ab = 12 or ab = 6. Using a = 3 we can find that b = 2.
- b^2 = 4 solves to b = 2 which matches with the previous value of b found.
Using a = 3 and b = 2, the sum of the values is a+b = 3+2 = 5, so that's why the answer is choice C.
Side note: 9x^2 + 12x + 4 factors to (3x + 2)^2
Answer:
= 6.577 × 10^-4
Step-by-step explanation:
Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is a.
Count how many places you moved the decimal point. This number is b.
If you moved the decimal to the left b is positive.
If you moved the decimal to the right b is negative.
If you did not need to move the decimal b = 0.
Write your scientific notation number as a x 10^b and read it as "a times 10 to the power of b."
Remove trailing 0's only if they were originally to the left of the decimal point.
Hope this helped

Answer:
2 or 3 im not sure but choes 2
Step-by-step explanation:
Answer:
x = 3
Step-by-step explanation:
2(4-3x) + 5(2x-3) = 20-5x
8 - 6x + 10x - 15 = 20 - 5x
-6x + 10x + 5x = 20 - 8 + 15
9x = 27
x = 3
