Answer:
(4k^2+7)(7k+6)
Step-by-step explanation:
1. group the first two terms (28k^3-24k^2). The greatest common factor is 4k^2. If you factor that out you get 4k^2(7k-6)
2.When you group the last two terms (49k-42). you can factor out a 7.
7(7k-6).
3. There is a (7k-6) in both sections so you can combine all the terms.
4k^2(7k-6) 7(7k-6) becomes (4k^2)(7k-6)
Answer:
1:2
Step-by-step explanation:
There are 18 nickles so that number is 18. When added together, there are 36 total coins. Since it states nickle to all coins, we replace <em>to</em> with a colon and replace the words with the related numbers.
18:36
like a fraction, ratios can be simplified. 18 is half of 36 so the ratio would go to 1:2. This means that 1 in every 2 coins is a nickle.
The Acute Angles Of An Isosceles Triangle Never Add Up To 90°.
Answer:
f(x)=7x−4 f ( x ) = 7 x - 4. Replace f(x) f ( x ) with y y . y=7x−4 y = 7 x - 4. Interchange the variables. x=7y−4 x = 7 y - 4. Solve for y y .
