Answer:

2×(6×²+3×-1)=18.

2×(6×3×+4)(6×4×-3)=144

2×(6×3×-2)(4×2+4×-6)=1154..

12×2=24

12×2+7×-12=60

12×2+25×-12=276

12×3+4×2-10×+12=76

12×3+4×2-26×+12=8

12×3+6×2-2=46

Help me solve this equation. Find f(x)-g(x)

mojhsa [17]

Answer:

- 2x³

Step-by-step explanation:

f(x) - g(x)

= $x^{\frac{1}{2} }$ - x - (2x³ - $x^{\frac{1}{2} }$ - x) ← distribute parenthesis by - 1

= $x^{\frac{1}{2} }$ - x - 2x³ + $x^{\frac{1}{2} }$ + x ← collect like terms )

= - 2x³

The mean of four consecutive even numbers is 15. The greatest of these numbers is a1. The least of these numbers is a2.

skad [1K]

X + (x + 2) + ( x + 4) + (x + 6)
-----------------------------------   = 15
   4

4x + 12
--------- = 15
    4

Multiply by 4 on both sides

4x + 12 = 60
subtract 12 from both sides
4x = 48
divide by 4 on each side
x = 12
x + 2 = 14
x + 4 = 16
x + 6 = 18

Simplify:0.3(x-2y)+0.5x-y

astraxan [27]

Answer:

0.3[x-2y] + 0.5x - y

Use the distributive property: a(b-c) = ab - ac

0.3x - 0.6y + 0.5x - y

Now, add/subtract all like terms

0.3x + 0.5x - 0.6y - y

0.8x - 1.6y

If you want, we can simplify that down further to:

0.8(x - 2y)
