Answer:

5x*5x=25^2=25x*25x=625x*625x

Step-by-step explanation:

First, 5x^2= 5x*5x. But, we can simplify this even more. It equals 25x^2 which is equal to 25x*25x. 25*25=625 but we still need the x's. So it would be 625x*625x idk it might be wrong

Finding values or<br> k(x) = x - 2<br> h(x) = x2 +1<br> (h + k)(2) =

Serjik [45]

Answer:

Step-by-step explanation:

$(h+k)(x)=h(x)+k(x)\\\\\bold{METHOD\ 1:}\\\\k(x)=x-2,\ h(x)=x^2+1\\\\(k+h)(2)=h(2)+k(2)\\\\\text{Calculate}\ h(2)\ \text{and}\ k(2).\\\text{Put}\ x=2\ \text{to the equations of the functions}\\\\h(2)=2^2+1=4+1=5\\k(2)=2-2=0\\\\\text\\\\\text{Substitute:}\\\\(h+k)(2)=5+0=5$

$\bold{METHOD\ 2:}\\\\k(x)=x-2,\ h(x)=x^2+1\\\\(h+k)(x)=h(x)+k(x)=(x^2+1)+(x-2)=x^2+x-1\\\\(h+k)(2)-\text{put}\ x=2\\\\(h+k)(2)=2^2+2-1=4+2-1=6-1=5$

Arnold needs to simplify the expression below.

Lunna [17]

Answer:

0.5x7

Step-by-step explanation:

Assuming that the original expression is $4.3*3+ 11(8.2-0.5*7)-6$ , according to PEMDAS multiplication takes priority over addition and subtraction,, and therefore, from the choices given, 0.5 * 7 must be performed first.

How would I solve this equation?

Assoli18 [71]

2(7/2)^x = 49/2

Divide both sides by 2:

(7/2)^x = 49/4

I notice that 49/4 can be rewritten as (7/2)^2, so we now have:

(7/2)^x = (7/2)^2

The only way for this to be true is if x = 2. Thus, we are done.
