5x^4-7(-x)
Would the simplified version of this be 5x^4+7x?
Answer:
5x⁴ + 7x or x(5x³ + 7 )
Step-by-step explanation:
Given expression:
5x⁴ - 7(-x )
To simplify this expression, we have to follow the order of operation PEMDAS;
Parentheses, Exponents, Multiplication, Division, Addition and Subtraction
5x⁴ - 7(-x ) = 5x⁴ + 7x
Since x is common to both terms;
= x(5x³ + 7 )
So the simplified version can be 5x⁴ + 7x or x(5x³ + 7 )
So given a rectangle with a perimeter of 40, and

What is 17 + -176 + 19 + 14 - -1723 + 3 / 9.
Order of operations.
Answer:
1597.3333333333
Step-by-step explanation:
= 17-176+19+14+1723+3/9.
= 17-176+19+14+1723+0.33333333333333
= -159+19+14+1723+0.33333333333333
= -140+14+1723+0.33333333333333
= -126+1723+0.33333333333333
= 1597+0.33333333333333
= 1597.3333333333

5(x – 4) = 3x + 4
A x = -8
(B) x = -2
C x=3
(D) x = 12
Math
Answer:
D
Step-by-step explanation:
5(x-4) = 3x + 4
5x-20 = 3x + 4
5x-3x-20= 4
2x=4 +20
2x=24
x=12
check answer by inserting 12 for x into original equation.
5(12-4) = 3(12) +4
5(8) = 36 +4

Answer:
The first one: if 2/3 is 12 then 1/3 is 6. 3/3 is 18. SO Jane had 18 stuffed animals before the donation.
The second one: 25 students then 13 are men so 25-13 is 12. 12/25 as a percentage is 48%
Hope this helps!
Answer:
[tex]Section \: A. \\before \: the \: donation \ : jane \: had \: \boxed{18 \: (stuffed \: animals)} \\
Section B.\\
\boxed{the\: percentage\: of\: female\: student\: is\: \boxed{48 \%}}
[/tex]
Step-by-step explanation:
[tex]Section A.\\let \: the \: total \: animals \: be \to \: t_{a} \\ let \: the \: donated\: animals \: be \to \: d_{a} \\ then \to \\ if \: d_{a} = \frac{2}{3} (t_{a} ) : we \: can \: find \: t_{a} \: by \to \\ 12 = \frac{2}{3} (t_{a} ) \\ 2(t_{a} )= 12 \times 3 \\ t_{a} = \frac{36}{2} \\ \boxed{ t_{a} = 18.}
\\ \\
Section B.\\
let \: the \: total \: number\: of \: students\: be \: be \to \: t_{s} \\ let \: the \: number\: of \: male\: student\: be \: be \to \: m_{s} \\ then \to \\ if \: t_{s} = m_{s} +1 3 \: then \\
m_{s} = t_{s} -13\\
m_{s} = 25-13 \\
m_{s} =12 \\
hence \: percentage \: of \: girls \: is = \frac{12}{25} \times 100 \\
the \: percentage\: is \to \boxed{m_{s} = 48\%}

A runner saved $25 when he purchased a pair of tennis shoes on sale. If the sale price was 35% off the regular price, what was the regular price of the tennis shoes?
Given:
Amount saved in sale = $25
Sale price was 35% off the regular price.
To find:
The regular price of the tennis shoes.
Solution:
Let the regular price of the tennis shoes be x.
Sale price was 35% off the regular price.
[tex]Discount=\dfrac{35}{100}x[/tex]
Amount saved in sale = $25
[tex]0.35x=25[/tex]
Divide both sides by 0.35.
[tex]x=\dfrac{25}{0.35}[/tex]
[tex]x=71.42857[/tex]
[tex]x\approx 71.43[/tex]
Therefore, the regular price of the tennis shoes is $71.43.
what are the possible degrees for the polynomial function
Answer:
Degree of the polynomial function = 5
Step-by-step explanation:
Since, the given graph of a polynomial has the x-intercepts at x = -2, -0.5, 0.5, 1.5, 3
Therefore, the equation of the polynomials with zero roots will be,
y = (x + 2)(x + 0.5)(x - 0.5)(x - 1.5)(x - 3)
When we solve this expression highest degree of the variable x will be 5.
Therefore, the possible degree of the polynomial function = 5
Answer:
i was going to screenshot the answer bc i got it right but its

Answer:
The answer is A cos(A)cos(B)
Step-by-step explanation:
I just took it
The expression which must fill in each blank space to complete step 3 is; Choice B; Cos(A)Cos(B).
Which expression must fill in each blank space?From the task content; It follows that the mathematical evaluation is in a bid to derive the Trigonometric identity for Tan (A-B).
From observation, it follows that the required expression is; cos(A)sin(B). This is because upon division of each term by the expression, the result is as in Step 4.
