The function is computed below based on the information. The answers will be:
1. -11
2. -1
<h3>How to compute the function?</h3>
f(x) = x²-11x+28
g(x) = x-4
(f+g)(-5) = (-5² - 11 × 5 + 28) + (-5 - 4)
= 25 - 55 + 28 - 9
= -11
(f-g)(5)
= = (5² - 11 × 5 + 28) + (5 - 4)
= 25 - 55 + 28 + 1
= -1

Step-by-step explanation: 26+M
Answer:
Option C = 335.5 in²
Step-by-step explanation:
Area of triangle = (1/2)×b×h
= (1/2)×a×a
= (1/2)×11×11
=60.5 in²
Area of rectangle = l×b
= b×a
= 25×11
= 275 in²
Area of pencil = Area of triangle + Area of rectangle
=60.5 + 275
335.5 in²
Answer:67,200
Step-by-step explanation: You multiply length×width×height.
Sorry If I am Wrong.
We can find the value of these 2 numbers by setting up 2 equations
x = first number
y = second number
by the what the first sentence in the problem says, we can say that:
6x + 2y = -8
by what the second sentence in the problem says, we can say that:
2x + 8y = 34
now that we have our 2 equations, we can use elimination to get rid of one of the variables. I am going to multiply the second equation by -3, so that we can add the 2 equations together and x will be eliminated.
-3(2x + 8y = 34)
-6x - 24y = -102
now we can add the 2 equations together and solve for y
6x + 2y = -8
-6x -24y = -102
-22y = -110
y= 5
now that we have the value for y, we can plug in 5 for y in either equation and solve for x,
6x + 2y = -8
6x + 2(5) = -8
6x + 10 = -8
6x = -18
x = -3
the two numbers are 5 and -3
hope this helped
