For question between 13 -> 17 replace n with the number.
Example:
13.) n = 2; 2+(-1) = 1
Answer by JKismyhusbandbae: 56 + 8x
Explanation: The distributive property says that the product of a number and a sum is equal to the sum of the individual products of the addends and the number. Using this information, multiply the value outside of the parentheses by each of the factors in the parentheses to write the equivalent equation.
5x9=49
Answer should be 49
Answer:
10 units
Step-by-step explanation:
Because the center of the circle is at (9 , 9) and passes through (4 , 9), <u>the radius must be 5.</u>
<em>Radius</em> - The length from the center of a circle to its edge
<em>Diameter</em> - The length from one edge of a circle to the opposite edge
The diameter is double the length of the radius, meaning D = 2(5).
2 × 5 = 10
So, the diameter of the circle is 10 units.
