How do you Subtract 9x^2 + 22x - 46 from 12x^2 - 8x + 12.
Luba_88 [7]

Subtract the x^2 terms from each other, then the x terms, then the ones without any x whatsoever.

(12x^2 - 8x + 12) - (9x^2 +22x-46)

First, we'll subtract 9x^2 from 12x^2

12x^2-9x^2- = 3x^2

Result: 3x^2

Next, we'll subtract 22x from -8x

-8x - 22x = -30x

Result: -30x

Finally, we'll subtract -46 from 12

12-(-46) = 12+46 = 58

Result: 58

Now, we can add these 3 results together.

First, we had 3x^2, then -30x, and finally 58.

Thus, our subtraction of

(12x^2 - 8x + 12) - (9x^2 +22x-46)

equals

3x^2-30x+58

Help its lateee and i suck at this

Answer:

1.  Identify the problem: Packaging boxes use too much material and create waste

2. What are the equations for the volume and surface area of a cube and rectangular prism?

Volume of a cube: Vcube = L x L x L = L3

Surface area of a cube: SAcube = 6 x (L x L) = 6L2

Volume of a rectangular prism: VRP = L x W x H = LWH

Surface area of a rectangular prism: SARP = 2 x (L x W) + 2 x (L x H) + 2 x (W x H) = 2(LW + LH + WH)

3. What is the difference in surface area of the packages below? (Note that they have the same volume.)

SAcube = 6L2

= 6 (20 cm)2

= 2,400 cm2

SARP = 2(LW + LH + WH) = 2 (20cm x 10cm + 20cm x 40cm + 10cm x 40cm) = 2,800 cm2

SARP – SAcube = 2,800 cm2

– 2,400cm2

= 400 cm

Step-by-step explanation:

everything in bold is the answer

7.003 x 10 to the power of 4
pishuonlain [190]
In scientific notation, just move the decimal point over however many numbers are in the power. 

In 7.003 • 10^4, move the decimal point over 4 places to the right, (or left if it's negative) making it 70,030
