The surface area would be 3 times 4 which is 12cm3
The domain is x<5 The range is all real numbers
Answer:
h(x) = 44
Step-by-step explanation:
h(x) = x² - 5, h(-7) means x = -7
h(x) = (-7)² - 5
h(x) = 49 - 5
h(x) = 44
Answer:
The two numbers are 31 and 19
Step-by-step explanation:
Let x and y be the numbers
x+y = 50
x-y = 12
Add the two equations together
x+y = 50
x-y = 12
-----------------
2x +0y = 62
Divide by 2
2x/2 = 62/2
x = 31
Now find y
31+y = 50
Subtract 31
y = 50-31
y = 19
