Answer:

$(12a^{5}-6a-10a^{3})-(10a-2a^{5}-14a^{4}) = 14a^{5}+14a^{4}-10a^{3}-16a$

Step-by-step explanation:

Given

$(12a^{5}-6a-10a^{3})-(10a-2a^{5}-14a^{4})$

Required

Simplify

We have:

$(12a^{5}-6a-10a^{3})-(10a-2a^{5}-14a^{4})$

Open brackets

$12a^{5}-6a-10a^{3}-10a+2a^{5}+14a^{4}$

Collect like terms

$12a^{5}+2a^{5}+14a^{4}-10a^{3}-6a-10a$

$14a^{5}+14a^{4}-10a^{3}-16a$

Hence:

$(12a^{5}-6a-10a^{3})-(10a-2a^{5}-14a^{4}) = 14a^{5}+14a^{4}-10a^{3}-16a$

Mary said that the best unit of measure to weigh her cat was ounces.Is she correct ?

fomenos

It depends but i would say yes because why you weigh a cat you want to show how much it is and be able to convert it.

X-y= 3 b) Work out the value of 2x - 2y c) Work out the value of y-x

givi [52]

Answer:

x - y = 3

x = 3 + y

y = x - 3

b) 2x - 2y

= 2(3+y) - 2( x - 3)

= 6 + 2y - 2x + 6

= - 2x + 2y + 12

Divide all terms by 2

we have

- x + y + 6

c) y - x

= x - 3 - ( 3 + y)

= x - 3 - 3 - y

= x - y - 6

I hope this helps you.
