Harry and Terry are each told to calculate 8−(2 5). Harry gets the correct answer. Terry ignores the parentheses and calculates 8−2 5. If Harry's answer is H and Terry's answer is T, what is H−T?GIVE U MANY POINTS!!!!!!!!!!

Answers

I'm pretty sure the space is a "+".

so the question was 8-(2+5) which is eual to (first the bracket) 8-7, which is 1

 H=1

if you ignore the bracket you have 8-2+5, which is (first the left side) 6+5, which is 11

T=11

and H-T=1-11=-10!

Enter the correct value so that each expression is a perfect-square trinomial.x2 – 10x +_____

Answers

Answer:

A = 25 so that the expression x^2-10x+A is a perfect-square trinomial.

Step-by-step explanation:

  Given : expression  x^2-10x+A

We have to find the value of A so that  each expression is a perfect-square trinomial.

perfect-square is the term in the form of (a+b)^2 \ or\ (a-b)^2

Since , we know the algebraic identity,

(a+b)^2=a^2+b^2+2ab\n\n (a-b)^2=a^2+b^2-2ab

Given expression x^2-10x+A is of the form of (a-b)^2=a^2+b^2-2ab

Thus, comparing , we get,

a= x ,

-2ab = -10x

⇒ b = 5

Thus adding b² term to get perfect-square trinomial.

b² = 25

Thus, the perfect-square trinomial becomes x^2-10x+25=(x-5)^2

So, A = 25

the answer is x2-10x+25 because that is half of -10 (5) squared
