Answer:
10 OR 8
Step-by-step explanation:
Area is length times width, so with that being said you could say 10 times 4 is 40 or you can say 8 times 5 is 40
Explain how to find the 52nd term using the explicit rule f(n)= 15n+10, then solve.
Answer:
790Step-by-step explanation:
Given the explicit rule function F(n) = 15n +10, in order to get the 52nd term of the sequence, we will have to substitute n = 52 into the rule given as shown;
f(52) = 15(52) + 10
f(52) = 780+10
f(52) = 790
Hence the 52nd term of the explicit rule is 790

Step-by-step explanation:
27x^6-152x^3+125=0
HELP ME AND PLEASE EXPLAIN!
Answer:
[tex]x=5/3\text{ or } x=1[/tex]
Step-by-step explanation:
We have the equation:
[tex]27x^6-152x^3+125=0[/tex]
We can solve this using u-substitution. Let's let u=x³. Therefore:
[tex]27(x^3)^2-152(x^3)+125=0[/tex]
Substitute all x³s for u:
[tex]27u^2-152u+125=0[/tex]
This is now in quadratic form. So, we can use the quadratic formula:
[tex]u=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
Our a is 27, b is -152, and c is 125. So:
[tex]u=\frac{-(-152)\pm \sqrt{(-152)^2-4(27)(125)}}{2(27)}[/tex]
Simplify:
[tex]u=\frac{152\pm\sqrt{9604}}{54}[/tex]
Simplify:
[tex]u=\frac{152\pm 98}{54}[/tex]
Reduce. Divide everything by 2:
[tex]u=\frac{76\pm49}{27}[/tex]
Split into two cases:
[tex]u=\frac{76+49}{27}\text{ or } u=\frac{76-49}{27}[/tex]
Solve for each case:
[tex]u=\frac{125}{27}\text{ or } u=\frac{27}{27}=1[/tex]
Substitute back x³ for our u:
[tex]x^3=\frac{125}{27}\text{ or } x^3=1[/tex]
Take the cube root of each equation:
[tex]x=\sqrt[3]{\frac{125}{27}}\text{ or } x=\sqrt[3]1[/tex]
Evaluate:
[tex]x=5/3\text{ or } x=1[/tex]
And that's our two solutions.
And we're done!
Solve for m.
-9 - m = -4 – 2m
m =
Answer:
m = 5
Step-by-step explanation:
-9 - m = -4 -2m
-m = -4 +9 - 2m
-m = 5 -2m
2m - m = 5
m = 5
Graph the solution to the following inequality.
Explanation= You basically do x=6 on the graph then you shade in the right side because that represents that x is GREATER THAN OR EQUAL to 6.

Step-by-step explanation:
Angelica is buying 5 tickets to the school musical. Tickets cost $7 each.
If c represents Angelica's total cost for tickets, which equation below is correct?
c = 5
c = 5 + $7
c = (5)($7)
c = $7
Hi!
Your answer should be: 3/c, "c= (5)($7)"
Reason being:
A: it only has the number of tickets, so that wouldn't make sense.
B: It has both numbers, but, were not adding, because the tickets cost $7 EACH, so only adding them wouldn't give you the right answer.
C: They are multiplying 5x$7, which is correct because each ticket is $7, and she is trying to buy 5, so 5x$7=c is correct.
D: like A, they only have one part of the problem, so it wouldn't make sense.
Hope this helps!
Yours truly,
~~~PicklePoppers~~~Answer:
I did this in a test so the answer is the third one. i already knew the answer was the third one.
Step-by-step explanation:
Lets check all of em first.
c = 5
(c) cant equal five because (c) is the total cost for tickets and if she bought 5
and each of them is $7 it cant be 5 thes goes same for the other- c = $7
Now for c = 5 + $7 Clearly you cant find out the total cost for 5 tickets using addition.
therefore, the right answer is c = (5) ($7)
15. Which statement explains why 30 is considered an irrational number?

Answer:
A. x+30
B. x+35
Step-by-step explanation:
A. Daniel
Since "Daniel is 30 cm taller than Katie" and "Katie's height is x cm", the expression will be x+30
B. Juli (sorry I can't type the full name due to Brainly system)
Since "Juli is 5 cm taller than Daniel" and Daniel is (x+30) cm, the expression will be (x+30)+5=x+35
John could not decide, but he had 9 dollars he could spend on fruit kabobs that cast 1.75 dollars and smoothies that cost 2.50 dollars. He knew he wanted at least one each. What are some combinations he could afford? Show at least three possibilities.
Answer:
One fruit kabob and one smoothie
Two fruits kabobs and two smoothies
Three fruit kabobs and one smoothie
One fruit kabob and two smoothies
Explanation:
In this situation, the basic combination John can afford is simply to buy one fruit kabob and one smoothie ( $1.75 + $ 2.50 = $4.25) because he wants at least one unit of each item. Additionally, it is possible to add more units of each item to create new combinations or possibles, just make sure they do not total more than 9 dollars, which is the money John has. Here are some of the possible combinations:
Two fruit kabobs and two smoothies
Fruit kabobs: $1.75 x 2 = $3.5
Smoothies: $ 2.50 x 2 = $5
Total: $8.5
Three fruit kabobs and one smoothie
Fruit kabobs: $1.75 x 3 = $5.25
Smoothie: $2.50
Total: $7.75
One fruit kabob and two smoothies
Fruit kabob: $1.75
Smoothies: $2.50 x 2 = $5
Total: $6.75

Answer:
1 + i[tex]\sqrt{5}[/tex], 1 - i[tex]\sqrt{5}[/tex]
Step-by-step explanation:
A quadratic function is f(x) = a[tex]x^{2}[/tex] + bx + c
Your function with the given values is f(x) = 2[tex]x^{2}[/tex] - 4x + 12
To solve a quadratic function, you can use the quadratic formula
(-b +/- [tex]\sqrt{b^{2} - 4ac}[/tex]) / 2a
Fill in with your given values.
(4 +/- [tex]\sqrt{(-4^{2} - 4 (2) (12)}[/tex] ) / 2(2)
Simplify
(4 +/- [tex]\sqrt{16 - 96}[/tex]) / 4
(4 +/- [tex]\sqrt{-80}[/tex] ) / 4
Because there is a negative number under the square root making it an imaginary number put an i by it.
(4 +/- i[tex]\sqrt{80}[/tex]) / 4
80 is divisible by 16, a perfect square. 80 / 16 = 5
(4 +/- 4i[tex]\sqrt{5}[/tex]) / 4
Divide by 4
1 +/- i[tex]\sqrt{5}[/tex]
Your teacher may want you to list your radical without the i and just as [tex]\sqrt{-5}[/tex], so keep that in mind.
Don't forget to list it both as addition and subtraction.
