This is my last question by the way

Leni [432]

Part A:

There are 25 blocks for the length, and the length of each is 5.5 inches. 5.5x25=137.5

There are 9 blocks for the height, and each is 2.75 inches. 2.75x9=24.75

Since we're trying to find how much longer the length is to the width, we find the difference. 137.5-24.75=112.75

So part A answer is 112.75 (or 112¾)

Part B:

We know the length is 137.5 and the height is 24.75. To find how many times longer the length is, we need to divide to see how many 24.75 can go into 137.5.

137.5÷24.75=5.55

So the answer to part B is 5.55. Given the context, the answer would probably be 5, because that's how many entire height can fit.

Sorry if it's wrong lol

Which system is equivalent to y= 9x^2 x+y=5 ?

melomori [17]

Answer : Option A

Explanation:

we can clearly see that from x+ y=5 we can substitute y = 5-x in y = 9x^2

Option B is clearly incorrect x can not be y -5

Option C is incorrect because y can not be 5 +x

Option D is incorrect because its y = 9x^2 not y^2 =9x^2 so y can not be 3x

if its y^2 = 9x^2 then only implies y = 3x

Translate the phrase into an expression: 11 more than one third of a number

skelet666 [1.2K]

1/3x+11.
1/3 of a number can be shown as 1/3x, since the number is not identified.

We can represent 11 more as +11.
This, our expression is 1/3x+11

Hope this helps!

Find a third-degree polynomial function with real coefficients and with zeros at -4 and -3 5i

Charra [1.4K]

If -3+5i is a solution, then by the conjugate root theorem, -3-5i is also a solution. We find the polynomial by multiplying together the factors. If x = -4, then x + 4 is the factor. If x = -3+5i, then (x-(-3+5i)) is a factor, and so is (x-(-3-5i)). Simplifying those down gives us as the first factor as (x+3-5i) and the second as (x+3+5i). We can FOIL those 2 together to get their product, and then FOIL in x+4. FOILing the 2 complex factors together gives us $x^2+3x+15ix+3x+9+15i-15ix-15i-25i^2$ . If we combine like terms and cross out things that cancel it's much easier than what it looks like there! It simplifies down to $x^2+6x-25i^2$ . Since i^2 = -1, it simplifies further to $x^2+6x-25(-1)$ and finally, to $x^2+6x+25$ . Now we will FOIL in x+4. $(x^2+6x+25)(x+4)=x^3+6x^2+25x+4x^2+24x+100$ . Our final simplified third degree polynomial is $x^3+10x^2+49x+100$

in your own words explain the place value relationship when the same two digits are next to each other in a multi digit number

zavuch27 [327]

I'll use 44.
This number broken down means 4 in the 10's place and 4 in the ones place
4(10)+4(1)= 40+4=44
