Answer:
C) -1.3
Step-by-step explanation:
|a| + b
Substitute a = -1.4 b = -2.7
|-1.4| + -2.7
Absolute values are positive
1.4 -2.7
-1.3
Answer:
Step-by-step explanation:
A scale factor of 1:3 means that one triangle is 3 times bigger than the other, for example. So, if the small triangle has a perimeter of 27, the big triangle has a perimeter 3 times as big.
No.
This rate of refusals seems quite low, actually. Some polls are lucky to get a 50% answer rate.
The trick here is to recognize one or more factors common to each term. For example, 6x4 − 24x3 + 72x2 = x^2(6x^2 - 24x + 72), so x^2 is one common factor. Looking at (6x^2 - 24x + 72), you can easily see that 6 is a common factor, so now we have (6)(x^2)(x^2 - 4x + 12). These last 3 terms do not have a common factor, so the factoring process stops here:
(6)(x^2)(x^2 - 4x + 12)
