Answer: Associative Property of Addition
Step-by-step explanation: The statement 7 + (4 + 4) = (7 + 4) + 4 represents the associative property of addition. Notice that the addends or the numbers we are adding are the same on both sides of the equals sign.
But on the left side, 4 and 4 are grouped together and on the right side, 7 and 4 are grouped together.
The <em>associative property of addition</em> says that when we are adding more than two numbers, the grouping of the addends does not affect the sum.
Here, the order operations tells us to begin inside the parentheses. So we have 4 + 4 which is 8 and 7 + 8 is 15.
On the right side, notice that 7 + 4 is 11 and 11 + 4 is also 15.
In general terms, we can write the associative property of addition as
(a + b) + c = a + (b + c) where <em>a</em>, <em>b</em>, and <em>c</em> are variables that can represent any number.
Answer:
I'm assuming we're solving for the hypotenuse, which is 21.5
Step-by-step explanation:
If a^2+b^2=c^2
Then 19^2+10^2 =461
This is c^2 so we must find the square root of 461
the square root of 461 is 21.47, or 21.5 rounded to the nearest tenth
Answer:
A=27/4 B=2.25
Step-by-step explanation:
4 and 1/2 also equals 18/4.
18/4+1/2(18/4)=18/4+9/4
18+9=27
Answer is 27/4
B)=4.5/2=2.25
X^3-2x^2-5x+6
From the shape, you can immediately tell it’s one of the x^3 functions. Then I just put both in my calculator and looked for which one matched
