Answer:
=21x2−13x+8
Step-by-step explanation:
=3x(7x−4)+−1(x−8)
=3x(7x−4)+−1x+(−1)(−8)
=3x(7x−4)+−x+8
Distribute:
=(3x)(7x)+(3x)(−4)+−x+8
=21x2+−12x+−x+8
Combine Like Terms:
=21x2+−12x+−x+8
=(21x2)+(−12x+−x)+(8)
=21x2+−13x+8

Please help me with this question.
Answer:
Area = 43.26
Step-by-step explanation:
There is a short way to do this.
Area = 1/2 s*t * Sin(R)
s = 14
t = 7
Area = 1/2 * 14 * 7 * Sin(62)
Area = 7 * 7 * sin(62)
Area = 49 * sin(62)
Area = 43.26
==================
There is another way you could do this.
Use the Cos law to find r
Then use Heron's formula to find the area. Trust me, you don't want to do that.
Doing the way I suggested gives 43.19. The difference is in what I did in the rounding. But I wouldn't want to type all the numbers.

Natasha's Bikes rents bikes for $16 plus $4 per hour. Micaela paid $36 to rent a bike. For how many hours (h) did she rent the bike
Answer:
Micaela rented the bike for 5 hours.
Step-by-step explanation:
Micaela paid $36 to rent a bike in Natasha's Bikes, where they charge a fixed fee of $16 plus $4 per hour.
We need to find the number of hours Micaela rented the bike.
From the $36 she paid, $16 was used to pay the fixed fee. Thus, the difference $36-$16=$20 was used to pay for the hours of rent.
Since the rate per hour is $4, then the number of hours is $20/$4 = 5 hours.
Micaela rented the bike for 5 hours.

Gabe is analyzing the plane ticket prices over the years. Comparing the cost of a plane ticket this year to last year, ticket prices are 12% higer than they were last year. Create an expression that represents the difference between this year and last year
Answer:
The difference in prices is 0.12x where x is the last year’s price
Step-by-step explanation:
Here, we want to create an expression
Let the price last year be x
12% more this year mean;
x + 12% of x
= x + 0.12x = 1.12x
So the difference between this year and last year will be;
1.12x - x = 0.12x

Answer:
The answer to #6 is 255
The answer to #7 is the mint milkshake is thicker
The answer to #8 is A is 12 and B is 18
The answer to #9 is A is 33 and B is 15
Missing values:
1. 1:7 , 3:21, 18:126
2. 20:12 , 10/3:2 , 8 1/3:5
3. 42:21 , 6:3 , 48:24
4. 4:10 , 8:20 , 16:40
5. 36:32 18:16
Step-by-step explanation:
#2: The first ratio is shown, which is 5:3. Meaning, that the bottom number (cakes) is multiplied by 5/3 in order to get the top number (pies). We can apply that to the ratio with 12 cakes, 12 multiplied by 5/3 is 20. The next ratio involved 10/3 pies. Since that is the "top" number (see chart), 10/3 need to be multiplied by 3/5 instead of 5/3. By doing that, the number of cakes is 2.
#7: The ratio of milk to ice cream in the mint milkshake is 1.25:4
The ratio of milk to ice cream in the strawberry milkshake is 1.75:5
When the ratios are divided, the quotient for the mint milkshake (0.3125) is LESS than the quotient for the strawberry milkshake (0.35). This means that there is less milk and more ice cream (ratio-wise) in the mint one.

108
Answer:
72 degrees
Step-by-step explanation:
Referencing off of line t being a straight line, a straight line is 180 degrees. If you subtract 108 from 180, you would get 72. Since this intersecting line is going through 2 paralel lines, the 2 groupings of angles reflect each other.

2/3=6/? means
2*6=3*?
2*3=6*?
2*?=3*6
2*?=3*?
Answer:
2/3 = 6/9
Step-by-step explanation:
2 x 3 = 6 so then you have to multiply 3 with 3 which is 9. (because the numerator and denominator should be multiplied by the same number.)
So thats why 2/3 = 6/9 is correct.
