Answer is D. 14
3 times 6 is 18 and minus 4 is 14
Answer:
d = 6
Step-by-step explanation:
multiply -3 by both things in equation
6 = 3d -12
6 + 12 = 18 ÷ 3 = 6
A right triangle contains a right angle, so it must have two sides that are perpendicular. If the slopes of two sides can be shown to be negative reciprocals of each other, then it can be concluded that a right angle is formed. If a triangle contains a right angle, then it is a right triangle.
Answer:

Step-by-step explanation:
The top number known as an exponent tells you to multiply the number by its self that many times so the other number will get very small.
Answer:
-3n²+n³
Step-by-step explanation:
Since the unknown number is n;
Product of the number and negative three is -3n
square of the number is n²
Taking their sum;
Sum = -3n + n²
Hence the sum of the product of the number and negative three and the square of the number is -3n+n²
If a number n is multiplied by the sum of the product of the number and negative three and the square of the number, hence the required function is;
f(n) = n(-3n + n²)
Expand
f(n) = -3n²+n³
This gives the required function
