Answer:
Positive
Step-by-step explanation:
Since x > 0 = x is positive
Since y < 0 = y is negative
Product of positive and negative number is negative.
Therefore,
xy = - xy
- (xy) = -( -xy)
- (xy) = xy [since product of negative and negative is positive]

Pat threw a football 5 more than twice the number of yards, y, which Gary threw. Which expression can be used to find the number of yards Pat threw the football? *
**SHOW WORKK PLS
Answers
Answer:
2y+5
Step-by-step explanation:
Lets start with an expression for how many yards Gary threw. Since y is the variable given in the problem, we'll use that.
Yards Gary threw = y
We also know that Pat threw 5 more than twice the yards Gary did. First, we multiply Gary's yards by 2, then add 5 more. We end up with the expression:
Yards Pat threw = 2y+5

Answer:
16b^4-9
Step-by-step explanation:
Factoring gives us 16b^4+12b^2-12^2-9. Simplifying gives us the answer which is 16b^4-9
Answer:
[tex]16b^4-9[/tex]
Step-by-step explanation:
When multiplying binomials, we can use a method called FOIL (First-Outside-Inside-Last).
For [tex](t_1+t_2)(t_3+t_4)[/tex], let:
[tex]t_1\implies \text{First Term},\\t_2\implies \text{Second Term},\\t_3\implies \text{Third Term},\\t_4\implies \text{Fourth Term}[/tex]
In the FOIL method, the steps go:
[tex]\text{\textbf{F}irst: Multiply the first and third terms (first term of each binomial)},\\\text{\textbf{O}utside: Multiply the first and fourth terms},\\\text{\textbf{I}nside: Multiply the second and third terms},\\\text{\textbf{L}ast: Multiply the second and fourth terms (last term of each binomial) }[/tex]
Given [tex](4b^2+3)(4b^2-3)[/tex], we have:
[tex]\text{First: }4b^2\cdot 4b^2,\\\text{Outside: }4b^2\cdot -3,\\\text{Inside: }3\cdot 4b^2,\\\text{Last: }3\cdot -3,\\\rightarrow 16b^4-12b^2+12b^2-9[/tex]
Combine like terms:
[tex]\boxed{16b^4-9}[/tex]

6 2/3 = x
Step-by-step explanation:
24 1/14 + 8 3/7 = (x ÷ 1 1/9) * 5 5/12
Add on the left by getting a common denominator
24 1/14 + 8 3/7*2/2 = (x ÷ 1 1/9) * 5 5/12
24 1/14 + 8 6/14 = (x ÷ 1 1/9) * 5 5/12
32 7/14 = (x ÷ 1 1/9) * 5 5/12
32 1/2 = (x ÷ 1 1/9) * 5 5/12
Changing to improper fractions
(2*32+1)/2 = (x ÷ 10/9) * (12*5+12)/12
65/2 = (x ÷ 10/9) * (65)/12
Multiply each side by 12/65
65/2 * 12/65 = (x ÷ 10/9) * (65)/12*12/65
6 = (x ÷ 10/9)
Copy dot flip
6 = x * 9/10
Multiply by 10 /9
6 * 10/9 = x * 9/10 * 10/9
60/9 =x
20/3 =x
Changing back to a mixed number
3 goes into 20 6 times with 2 left over

Answer:

Step-by-step explanation:
[tex](24+8)+(\frac{1}{14} +\frac{3}{7})=(x:\frac{10}{9}).\frac{65}{12}\\32+\frac{1}{2}=(x.\frac{9}{10}) .\frac{65}{12} \\32\frac{1}{2}=(\frac{9}{10}x).\frac{65}{12} \\\frac{65}{2}=\frac{9}{10}x.\frac{65}{12} \\\frac{65}{2}=\frac{3}{2} x.\frac{13}{4} \\\frac{65}{2} =\frac{39}{8} \\\frac{20}{3} =x\\x=\frac{20}{3}[/tex]

Volume = 66
Surface are = 144
Step-by-step explanation:
1. Volume
The formula to find the volume of a triangular prism is the following,
[tex]A=\frac{l*w*h}{2}[/tex]
The following information is given,
lenght = 4
width = 11
hieght = 3
Substitute these numbers into the formula and solve for the heihgt,
[tex]A=\frac{l*w*h}{2}\\\\A=\frac{4*11*3}{2}\\\\A=66[/tex]
2.Surface area
The surface area of a figure is the two-dimensional distance around the figure. It can be found by finding the area of each face of the figure and then adding the result up.
The formula to find the area of a rectangle is the following,
[tex]A_r=(lenght)(width)[/tex]
The formula to find the area of a triangle is the following,
[tex]A_t=\frac{(legnth)(width)}{2}[/tex]
Substitute in the give values and add up the results to find the total surface area of the rectangle,
[tex]((5)(11))+((4)(11))+((3)(11))+(\frac{(3)(4)}{2})+(\frac{(3)(4)}{2})\\\\=55 + 44 + 33+ 6 + 6\\\\= 144[/tex]

Simplify the expression by combining like terms: x + 7x
Answers
Answer:
Like terms means that the numbers have the same variable after them or they don't have a variable at all. It is also important to remember that any letter that doesn't have a number in front of it technically has a 1 in front of it.
For example, x + 3x = 1x +3x. Then I add the numbers in the front and I get 4x.
If it had been 4x + 7x + 3, my answer would have been 11x +3. That's because there were a total of 11 x, but the 3 ones weren't x's so I just leave them alone.
Step-by-step explanation:
Answer:
[tex]8x[/tex]
Step-by-step explanation:
