Answer:

Step-by-step explanation:

I remember dividing whole numbers being HARD, and I mean HARD HARD HARD. but I got over it.

It really depends on HOW you're dividing the whole numbers. Into thirds, fourths, halves, and WHAT the number itself is. Remember to specify your question!

What is the area of this rectangle? Provide supportive evidence so I can learn better about this. I’m having troubles.

Katyanochek1 [597]

Answer:

the answer is 15x^8 y^3

Step-by-step explanation:

the area of a rectangle is length times width right? this means you have to multiply the values that represent the length and width. in this case those values would be 5x^6 y^2 and 3x^2 y

step 1. set up your problem

it should look like this:

(5x^6 y^2)(3x^2 y)

step 2. multiply the values with corresponding variables

first, x values

(5x^6)(3x^2)

5×3=15 and x^6 × x^2=x^8 when multiplying exponents you add the powers the numbers are raised to. in this case 6+2=8

you should end up with 15x^8

next, y values

y^2 + y

remember what i said about multiplying exponents? you just add the power the variables are raised to. in this case, 2 and 1. when their is no exponent we just add a 1. so, 2+1=3

you end up with y^3

lastly, combine

15x^8 + y^3 = 15x^8y^3

Mandarinka [93]

Answer:

The standard form of the equation is 49t² - 75t + 3 = 0

The solution of the equations are 1.49 and 0.041

Step-by-step explanation:

* Lets explain how to solve the problem

- The standard form of the quadratic equation is ax² + bx + c = 0,

where a , b , c are constant and a can not be 0

∵ The quadratic equation is -4.9t² + 7.5t + 1.8 = 2.1

- Lets make the left hand side equal to 0

∵ -4.9t² + 7.5t + 1.8 = 2.1 ⇒ subtract 2.1 from both sides

∴ -4.9t² + 7.5t - 0.3 = 0 ⇒ multiply each term by -10

∴ 49t² - 75t + 3 = 0

* The standard form of the equation is 49t² - 75t + 3 = 0

∵ ax² + bx + c = 0

∴ a = 49 , b = -75 , c = 3

- Lets use the formula $x=\frac{-b+-\sqrt{b^{2}-4ac}}{2a}$ to solve

the equation

∴ $x=\frac{-(-75)+\sqrt{(-75)^{2}-4(49)(3)}}{2(49)}=1.49$

∴ $x=\frac{-(-75)-\sqrt{(-75)^{2}-4(49)(3)}}{2(49)}=0.041$

* The solution of the equations are 1.49 and 0.041
