Expand and simplify ([tex]2x^{2}[/tex]+3)(4x+5)-8x([tex]x^{2}[/tex]-2)
Answers
Answer:
2x(5x + 14) + 15
Step-by-step explanation:
Given: (2[tex]x^{2}[/tex] + 3)(4x + 5) - 8x([tex]x^{2}[/tex] - 2)
(2[tex]x^{2}[/tex] + 3)(4x + 5) - 8x([tex]x^{2}[/tex] - 2) = 2[tex]x^{2}[/tex](4x + 5) + 3(4x + 5) - 8x([tex]x^{2}[/tex] - 2)
= (8[tex]x^{3}[/tex] + 10[tex]x^{2}[/tex] + 12x + 15) - 8[tex]x^{3}[/tex] + 16x
= 8[tex]x^{3}[/tex] + 10[tex]x^{2}[/tex] + 12x + 15 - 8[tex]x^{3}[/tex] + 16x
collecting like terms to have,
8[tex]x^{3}[/tex]- 8[tex]x^{3}[/tex] + 10[tex]x^{2}[/tex] + 12x + 16x + 15
10[tex]x^{2}[/tex] + 28x + 15
Thus,
(2[tex]x^{2}[/tex] + 3)(4x + 5) - 8x([tex]x^{2}[/tex] - 2) = 10[tex]x^{2}[/tex] + 28x + 15
= 2x(5x + 14) + 15

2x+y=17 in slope intercept form
Answers
Answer:
y=-2x+17
Step-by-step explanation:
So the problem is 2x+y=17, we know that slope intercept form is y=mx+b where m is the slope and b is the y-int.
All you have to do is isolate the y.
2x+y=17
-2x on both sides so you can leave the y alone.
y=-2x+17 should be the answer. Hope this helps!

A cell phone normally sells for $500, but it is marked down 30% and you have a coupon for an additional 15% off. How much would it cost you to purchase the cell phone?
Answers
Answer:
$275
Step-by-step explanation:
30% + 15%=45%
45% of 500 is 225, because 500 x 0.45=225. Then subtract the discount from the total, 500 - 225, and you get 275

Step-by-step explanation:

Solving this equation using the quadratic formula, we get two real solutions :

If f(x) = 5 + 4(x - 4)?,
what is f(7)?
Answers
Answer:
Let's solve for f.
x=5+4(x−4)f(7)
Step 1: Flip the equation.
28fx−112f+5=x
Step 2: Add -5 to both sides.
28fx−112f+5+−5=x+−5
28fx−112f=x−5
Step 3: Factor out variable f.
f(28x−112)=x−5
Step 4: Divide both sides by 28x-112.
f(28x−112)28x−112=x−528x−112
f=x−528x−112
Answer:
f=x−528x−112

Bryan’s mile per hour = 4
4 miles per hour
You drive a car that runs on ethanol and gas. You have a 20 gallon tank to fill and you can buy fuel that is either 25% or 85% ethanol. How much of each fuel should you buy to have 50% ethanol in the tank? Will give brainliest!!!!!!!!!!!!!!!!!!
Answers
Answer:
11.67 gallons of 25% and 8.33 gallons of 85%Step-by-step explanation:
Let the volume of 25% ethanol be x, then volume of 85% ethanol will be (20 - x)
The ethanol content is:
0.25x + 0.85(20 - x) = 20*0.50.25x + 17 - 0.85x = 10-0.6x = 10 - 17-0.6x = -7x = 7/0.6x = 11.6711.67 gallons of 25% ethanol and
20 - 11.67 = 8.33 gallons of 85% ethanol
On that day the bakery gave away a total of 29 free gingerbread man cookies what was the total number of free candy canes the bakery gave away on that day show how or explore how you got your answer
Answers
Answer: 19 people
Step-by-step explanation:
If every 4th customer received a free gingerbread man cookie and 29 cookies were given away then the number of customers that came were:
= 4 * 29
= 116 customers
Because 116 customers came, they were able to give 29 cookies by giving one to every 4th customer.
If there were 116 customers, the number of customers who got the free candy canes would be:
= 116/6
= 19.3
= 19 people

Step-by-step explanation:
complementary anlges add up to 90º. so, we can make an equation:
x+x-10=90
2x=100
x=50
so the angles are 50º and 40º.
