Answer:
1. -2x+24
2. 3x+21
3. 5x-17
4. 3x²+12x
5. 18
Step-by-step explanation:
2. 3(x)+3(7)=3x+21
3. 5(x)+5(-4)+3= 5x-20+3=5x-17
4. 3x(x)+3x(4)=3x²+12x
5. 3(10)-12=30-12=18
The answer is -60x + 56
4(6 - 5x) + 8(4 - 5x)
24 - 20x + 32- 40x
56 - 60x or you can write it as -60x + 56
It is 28 pounds. This is because all of the others have a ratio of 4:1 while 28 and 5.5 have a ratio of 56:13.
The answer is C it’s vertex is at (2,4) because a quadratic formula is suppose to look like y= a ( x - h )^2 + k and the vertex is (h,k) when you look back at Your question h=-2 and but Bc of the formula then it’ll be h=2 and then k=4 and that’s how you get the vertex from a quadratic formula. Hope this helps :)
