Circle the problem in wich you need to regroup. Use the strategy that is easier to find the sum. A) 496+284. B) 482+506

1 answer:

5 0

B, because I’m A, it has no number to regroup from(all the numbers can go into each other when yo add) In B, 6 can’t go into 2, so you’ll need to regroup, - hopefully this helped and hopefully I get the answer correct

Answer: PLEASE GIVE BRAINLIEST

72 integers

Step-by-step explanation:

Starting From 82-174 every integer is included in T so every integer that is not included in T but included in R would be 82-10 so every integer from 10 to 82.

Help with #4 please

Slav-nsk [51]

For a circle, the circumference can be found by multiplying /pi by the diameter. In this case, 'x' appears to be the diameter of the circle meaning 'y' would be the circumference.

Someone help me with this question ASAP and show work please and thank you

Answer:

g(f(x)) = x

Step-by-step explanation:

You are given f(x) = -4x - 1 and g(x) = $\frac{x+1}{-4}$ . Keep in mind that f(x) or g(x) is the same as a y = equation, but two separate equations.

You are trying to find g(f(x)), which means that you will use f(x) and substitute this value into the x value in the equation of g(x).

It will look like: g(-4x - 1) = $\frac{x+1}{-4}$

$\frac{(-4x-1)+1}{-4}$

Now evaluate the expression to solve the problem. Start by combining like terms.

$\frac{(-4x)}{-4}$

You are left with -4x/-4. We can simplify this even further by dividing both sides of the fraction by -4/-4. The -4's cancel out and become 1's, so you are left with:

$x$

Factor: m^2 - 20m - 21

Anton [14]

Answer: (m-21)(m+1)

Step-by-step explanation:

To factor this trinomial, find two numbers that multiply to -21 and add to -20:

(-21)(1)=-21

-21+1=-20

They are -21 and 1.

Add -21 and 1 to m to get both factors:

(m+(-21)) and (m+1)

(m-21) and (m+1)

Multiply them to get the answer:

(m-21)(m+1)
