harina [27]

Answer:

5a^2+12b^2-40b

Step-by-step explanation:

First distribute the -4 to the 2b and -3b. This leaves you with 5a^2-8b+12b(b+4)

Now you can distribute the 12b to b and +4. This leaves you with 5a^2-8b+12b^2+48b

Now you can combine your like terms leaving you with 5a^2+12b^2-40b.

Combine the like terms to create an equivalent expression: <br> 2s+(−4s)=?
Sergeeva-Olga [200]

Answer:

2s+\left(-4s\right)=-2s is the equivalent expression as 2s+\left(-4s\right) is equal to -2s.

Step-by-step explanation:

Considering the expression

2s+\left(-4s\right)

As we know that

  • Like terms are said to be the terms which hold the same variables raised to the same power.
  • For example, 3x and 2x are like terms as they contain the same variable x raised to the same power.

Lets solve the expression

2s+\left(-4s\right)

\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a

2s-4s

\mathrm{Add\:similar\:terms:}\:2s-4s=-2s

-2s

Therefore,

2s+\left(-4s\right)=-2s is the equivalent expression as 2s+\left(-4s\right) is equal to -2s.

I need help if anyone knows the answer please ASAP
mina [271]

Answer:

TE=11

Step-by-step explanation:

x^2+6x=x+14\\x^2+6x-x-14=0\\x^2+5x-14=0\\(x-2)(x+7)=0\\x=2\\x=-7\\

(you can't use -7 cuz that would make TE a negative distance and that's a nono)

x=2\\TE=6(2)-1\\=12-1\\=11
