Step-by-step explanation:
multiply the first equation by 1, the second by -1 and add.
x + 2y = -16
-x - 6y = 28
--------------------
0 - 4y = 12
-4y = 12
y = -3
x + 2×-3 = -16
x - 6 = -16
x = -10
Answer: The answer is D sowwy if im wrong
Step-by-step explanation:
We multiply the outside exponent 3 to every variable in the parenthesis. We multiply -3, 3 times to 3c because the exponent of -3 is going in -3 -3 -3 times which is -27 this is because -3 is a whole number
3 times -3 ^-3 ^-3 = -27
3 times 3 = 9
5 times 3 = 15
-9c^9w^15
Y = -3/5x + 5.4 is the answer
Answer:
No because the 6+4 does not equal 36.
Step-by-step explanation:
first make the hypotenuse 6 the other two are sides A and B
Use the pythagorean theorem: 3^2+2^2+6^2
6+4=36
Answer:
5656 m^3
Step-by-step explanation:
Volume of a cylinder can be calculated using below formula
V = πr²h
Where
h= height =18m
r= radius= radius = 10m
If we substitute the values we have
V = π × (10)²× 18
= 5655.6 m^3
= 5656 m^3
