Multiply the first bracket by -4. Multiply the second bracket by -2
-8x+12y+4x-2x-12
Negative and Negative = Positive
Negative and Positive = Negative
Then do -8x+4x-2x
= -6x+12y-12
Answer is D. -6x+12y-12
Answer:
circumference of a circle = 2*pi*radius
just multiply 3.14 (pi) by 2 by the radius/diameter divided by 2
3/4 is not P. Because 3 out of the 4 quadrants is not purple.
Given:
.
To find:
The value of 
, rounding to the nearest thousandth.
Solution:
We know that,
On substituting , we get
Therefore, the value of is 0.646.
Answer: 2x3 + 17x2 + 25x - 50
Step-by-step explanation: Just try to distribute it at every step as follows:
Step 1: Start with the following:
(a + b + c)(d + e)
Step 2: Distribute (d + e) to each of the term in the first parenthesis
a(d + e) + b(d + e) + c(d + e)
Step 3: Distribute d and e to each term:
(ad + ae) + (bd + be) + (cd + ce)
or ad + ae + bd + be + cd + ce without the parentheses.
Step 4: Finally, simplify.
Using the above you should be able to do the following
Step 1: (2x2 + 7x - 10)(x + 5)
Step 2: 2x2(x + 5) + 7x(x + 5) - 10(x + 5)
Step 3: 2x3 + 10x2 + 7x2 + 35x - 10x - 50
Step 4: 2x3 + 17x2 + 25x - 50
