Answer:
d
Step-by-step explanation:
100x² - 1 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b), thus
100x² - 1
= (10x)² - 1²
= (10x - 1)(10x + 1) → d
You would move over the -2 making the equation look like this 4x>3x+7. Then move the 3x to the other side of the equation making it look like this 1x>7. Thus the answer is x>7.

Answer: x = 8
Step-by-step explanation: 1/4(x+12)=5 is the same as 1/4x + 3 = 5. 1/4 of 8 is 2. 2+3=5.
Answer:
The product of the tens in these two numbers is 4
Step-by-step explanation:
TO find this, first we need to find the number in the tens place for each of them. The tens place is the second from the decimal point.
14
42
Now we take these two and multiply them together to get the product.
1 * 4 = 4
