What did i do wrong?

irakobra [83]

Answer:

27x +42+ 3x²

Step-by-step explanation:

so im learning this rn in class and what you do is FOIL

So its stands for

First

Outside

Inside

Last

(3x+6)(x+7)

(3x+6)(x+7) -- 3x² (if you have x times x it is x to the second power)

(3x+6)(x+7) -- 21x

(3x+6)(x+7) -- 6x

(3x+6)(x+7) -- 42

Now add 21x and 6x

27x +42+ 3x²

you must have added the 21 and 6 incorrectly.

Kyle and Taylor ran laps after school to train for the baseball team. The ratio of the number of laps Kyle ran to the number of

Zinaida [17]

Answer:

9 laps.

Step-by-step explanation:

-Let x be the number of laps Taylor runs.

-Given that the ratio of Kyle to Taylor laps is 2:3, we express the actual laps in meters to solve for x as follows:

$\frac{Kyle}{Taylor}=\frac{2}{3}\\\\\therefore \frac{2}{3}=\frac{6}{x}\\\\2x=18\\\\x=9$

Hence, Taylor runs 9 laps.

5/7^3 = 5(7^x)<br> Thank you for helping!!

SIZIF [17.4K]

When solving this equation you get x = -3.

To solve this, simply follow the order of operations for solving.

$\frac{5}{7^{3}} = 5(7^{x} )$ ----> start by dividing both sides by 5

$\frac{1}{7^{3}} = (7^{x} )$ -----> Now you can transform the front side of the equation to use negative exponents.

$7^{-3} = 7^{x}$

Since both x and -3 are the powers of x, we can eliminate the 7 and just make the exponents equal.

-3 = x
