Evaluate the expression for x = 4: 6+ (10 - x)2 - 20

1 answer:

4 0

6 + (10 - 4)2 - 20 = 6 + 12 - 20 = 18 - 20 = -2

Assuming that the two in the middle of the expression is multiplied by (10 - x) the answer would be -2. I apologize if I did not read your question right.

Answer:

$14^{-17}$

Step-by-step explanation

using the rules of exponents, it would be $14^{10}$ ÷ $14^{27}$ so then take away 27 from 10 and get -17 meaning that the answer would be A or $14^{-17}$

(2a+b)^2 how do you do this

gulaghasi [49]

• Expand (2a + b)²:

(2a + b)²

= (2a + b) · (2a + b)

Multiply out the brackets by applying the distributive property of multiplication:

= (2a + b) · 2a + (2a + b) · b

= 2a · 2a + b · 2a + 2a · b + b · b

= 2²a² + 2ab + 2ab + b²

Now, group like terms together, and you get

= 2²a² + 4ab + b²

= 4a² + 4ab + b² <——— expanded form (this is the answer).

I hope this helps. =)
