Answer:
a) 3x^2 + x - 2
b) 28m
Step-by-step explanation:
a) Since the Area for a normal square is b*l (base x length)
Do the same with this (Using FOIL ig)
(3x - 2) * (x + 1)
3x^2 + 3x - 2x - 2
3x^2 + x - 2
b) Since it's asking us to find out what the number will be while x = 3m, just substitute 3 for every "x" in the answer we got for a
3(3)^2 + (3) - 2
3(9) + (3) - 2
27 + 3 - 2
30 - 2
28m
Therefore the actual area of this rectangle is 28m

8xy^3*xy ^8 plsssssssssssssssssssss help
Answer:
x • (x^3 - 3x^2y + 3xy^2 + 7y^3)
Step-by-step explanation:
(8x • (y^3)) + x • (x - y)^3
2^3xy^3 + x • (x - y)^3
Evaluate : (x-y)^3 = x^3-3x^2y+3xy^2-y^3
Pull out like factors :
x^4 - 3x^3y + 3x^2y^2 + 7xy^3 =
x • (x^3 - 3x^2y + 3xy^2 + 7y^3)
x^3 - 3x^2y + 3xy^2 + 7y^3 is not a perfect cube

Sam does a weekly exercise program consisting of cardiovascular work and weight training. Each week, he exercises for at least 5 hours. He spends at most 3 hours doing cardiovascular work. He spends at most 11 hours on weight training. Let x denote the time (in hours) that Sam spends doing cardiovascular work. Let y denote the time (in hours) that he spends on weight training. Shade the region corresponding to all values of x and y that satisfy these requirements.

need help dont understand it
Answer:
It is Linear Increasing.
Step-by-step explanation:
If it is a straight line, it is a linear function. if it is NOT a straight line, then it is a non-linear function.
Edit: When the line starts from the top of the y-axis, then it is decreasing. If the line starts from the Origin Point (as shown in the picture you included), then it is increasing. I hope this helps you in Linear and Non-linear relationships.
What is the value pls help
Answer:
n = 27
Step-by-step explanation:
Multiplication has the commutative property, which means it doesn't matter what way around you put the numbers e.g. 4 × 3 = 3 × 4
So 27π = 27 × π = π × 27
n is 27

which line is parallel to the line whose equation is 4x 3y = 7, and also passes through the point (- 5, 2)?
Answer: [I assume: "4x 3y = 7" is really 4x + 3y = 7]
y = -(4/3)x -14/3
Step-by-step explanation:
Rewrite this as y=mx+b, where m is the slope.
4x + 3y = 7
3y = -4x +7
y = -(4/3)x +(7/3)
The slope is -(4/3)
A parallel line will have the same slope, but a specific value of b to allow it to go through the given point (-5,2):
y = -(4/3)x + b
Enter the point and solve for b:
2 = -(4/3)(-5) + b
2 = (20/3) + b
b = 2 - (20/3)
b = 6/3 - 20/3
b = -14/3
y = -(4/3)x -14/3

Rewrite the equation in Ax+By=C form.
Use integers for A, B, and C.
y+ 6 = 5(x-3)
Answer:
5x - y = 21
Step-by-step explanation:
Given the linear equation in point-slope form, y + 6 = 5(x - 3):
In order to transform the given equation into its standard form, Ax + By = C, start by distributing 5 into the parenthesis:
y + 6 = 5(x - 3)
y + 6 = 5x - 15
Subtract 5x from both sides:
- 5x + y + 6 = 5x - 5x - 15
- 5x + y + 6 = - 15
Subtract 6 from both sides:
- 5x + y + 6 - 6 = - 15 - 6
- 5x + y = - 21
Divide both sides by -1:
[tex]\frac{-5x + y}{-1} = \frac{-21}{-1}[/tex]
5x - y = 21
(4,-3),m=-1 in standard form
Answer:
Step-by-step explanation:
m = -1 ; ( 4 , -3)
y - y1 = m(x - x1)
y - (-3) = -1(x - 4)
y+ 3 = -x + 4
Add x to both side.
x +y + 3 = 0
Subtract 4 from both sides
x + y + 3 - 4 = 0
x +y - 1 = 0
-½(x + 1¼) = - 3 + ¼x

hoose the statement that describes its

3(x + 8) - 9x = 6(4- x)
O There is no solution.
оо
There is only one solution.
ws
о
All real numbers are solutions.
Answer:
3rd option
Step-by-step explanation:
3(x + 8) - 9x = 6(4 - x) ← distribute parenthesis on both sides
3x + 24 - 9x = 24 - 6x , collect like terms on left side )
24 - 6x = 24 - 6x
Since both sides are the same then any value of x will make the equation true.
That is all real numbers are solutions
Answer: C g(x) is a function because f(x) is one-to-one.
Step-by-step explanation:
pls help me with this if you can
1) Let L = the larger # and S = the smaller #.
A large # is 5 more than twice a smaller #.....This gives Eq 1) L = 5 + 2S
Their sum is 80...This gives Eq 2) L + S = 80.
Substitute Eq 1) into Eq 2), you get
L + S = 80
5 + 2S + S = 80
3S = 75
S = 75 / 3 = 25
L = 5 + 2S
= 5 + 2(25)
= 5 + 50
= 55
