A=L•H that’s the equation you will use.
Length= 3
Height= 4
4•3=12, your answer is 12.

The area of the rectangle is 12 square foot because in or to determine the area you need to multiply the length times height.

How do you do this and is this correct

loris [4]

Yes that is right so you just plug in the days as x then multiply the new x with the number to the left of it then add the number on the right and finally that is your y

-9=u+9/-4 what steps do we take to solve for the variable u?

daser333 [38]

Answer:

you want to isolat U on one side, so subtract 9/-4 from both sides to end up with (9/-4) - 9 = u, then solve. (9/-4)-9 = -11.25, so -11.25 = u

Perform the specified operations on the polynomials: Subtract 2x2−3xy+4y2from 3x2−5xy−6y2

tankabanditka [31]

Answer:

Solution to the given expression is $(x^2 -10y^2 -2xy)$

Step-by-step explanation:

Here, the given expression are:

$P(x) = 2x^2- 3xy+4y^2\\Q(x) = 3x^2 - 5xy-6y^2$

To Solve for : Q(x) - P(x)

Now substitute the value of P(x) and Q(x) , we get:

$Q(x) - P(x) = P(x) = (3x^2 - 5xy-6y^2) - (2x^2- 3xy+4y^2)\\= 3x^2 - 5xy-6y^2 - 2x^2+3xy-4y^2\\=x^2-10y^2-2xy\\\implies Q(x) - P(x) = (x^2-10y^2-2xy)$

Hence solution to the given expression is $(x^2 -10y^2 -2xy)$

GIVING BRAINLEST TO THE PERSON THAT CAN EXPLAIN HOW TO DO THIS THE BEST :)

WINSTONCH [101]

Answer:

530 m²

Step-by-step explanation:

First of all we need to label the missing sides ,please check the figure I provided for that :

x = 37 - (10+ 15) = 37 - 25 = 12

z = 10

y = 2 × 10 = 20

The shade does area = area of the whole rectangle − the white area

= 37 × 20 − [ (15×20)÷2 + (10×12)÷2 ]

= 740 − [ 150 + 60 ]

= 740. − 210

= 530
