Answer:
12
Step-by-step explanation:
Use pythag to solve.
x^2+5^2=13^2
x=12
Answer:
Step-by-step explanation:
A = 6² + 4(½(6)(6))
A = 108 in³
False.
Replace x with 0 and solve:
2(0) + 3 = 0+ 3 = 3
3 is not greater than 13 so the answer is false.
Answer:
x+4y=-35
-8x-4y=28
Step-by-step explanation:
The answer to the original equations is (1, -9). You can solve that by using substitution by moving the 4y over and substituting that equation for x on the second part of the top equation. Using elimination, the second set of answers will give you the same, (1, -9)!
Answer:
There is no real solution
Step-by-step explanation:
If you are finding the square root of a number, it cannot be negative. No number can be multiplied by itself to get a negative number. Negative numbers multiplied with themselves make a positive number. Positive numbers are obviously going to stay positive. Therefore there is no square root of -9
