Answers:
Step 1 is distributive property
Step 2 is distributive property (again)
Step 3 is commutative property
===============================================
Explanation:
The distributive property is the idea of multiplying the outer value by each inside value in the parenthesis. In general, the rule is a*(b+c) = a*b+a*c. We have the outer term 'a' multiplied by each inner term b and c. Then we add the products. The distributive property is used twice to multiply the two binomials. Your teacher and/or book may refer to it as the FOIL rule. FOIL stands for "first, outer, inner, last" which is a handy way to remember the order in how to multiply binomials.
The commutative property is the idea of adding or multiplying two values in any order we want. In this case, we're focusing on adding. This allows us to swap the terms to go from -5y^2+9x^2 to 9x^2+(-5y^2) = 9x^2-5y^2
Answer:
10 pounds. Hope this helps!!!!
Step-by-step explanation:
If 2 pound serves 8 people you can express that as a ratio of 2:8 so to get 8 people to 40 you multiply by 5 so you must do the same for the amount of pasta so 2 multiplied 5 equals 10.
That could be expressed in two different ways ... because
there are no parentheses in your question.
One way:
Call the number ' N ' .
Nine plus the number is (9 + N)
That much times 14 is 14(9 + N) .
The other way:
Call the number ' N '.
The number times 14 is 14N
Nine plus that is 9 + 14N .
In order to find the x-intercept we need to make y=0
Then we isolate the x
x y Ordered Pair type of intercept
0 0 (0,0) x-intercept
Now for the y-intercept we need to make x=0
we isolate the y
0 0 (0,0) y-intercept
ANSWER
0 0 (0,0) x-intercept
I'm not sure but I hope this helps
4+8x and 4 (2x+1)
4+16 and 4 (4+1)
20 and 4 (5)
20 and 20
