Answer: 1 gallon

Step-by-step explanation:

Hi there!

Using the equation (12*18)-(7*3), where 12*18 is the area of the wall, 7*3 is the area of the door not being painted, you are left with 196 square ft. of wall. further dividing 196/200 is 0.98, meaning that Mr. Smith will only need one gallon of paint for his wall.

[(12*18)-(7*3)]/200

(215-21)/200

196/200

0.98

EMERGENCY OOF HELP WITH MATH PIZZZ<br><br> 5 + x^2= 2x^2+ 13<br><br> Provide steps and thanks
galben [10]

Answer:

false statement

Step-by-step explanation:

5+x^2=2x^2+13

5+x^2-2x-13=0

-8+x^2-2x^2=0

-8-x^2=0

-x^2=8

x^2=-8

this statement is false for any value of x because the power function with an even exponent is always postive or 0

!TWELVE POINTS + BRAINLIEST ANSWER! Write the equation for an ellipse with y intercepts (0,-3) and (0, 3) and major axis of leng
Mandarinka [93]

Answer:

x²/25 + y²/9 = 1  or 9x² + 25y² = 225

Step-by-step explanation:

We have two points which is y intercepts (0,-3) and (0,3).

We know that the major axis is 2a and secondary axis is 2b

These two points are vertical top of the ellipse which they give us value of half secondary axis  b = 3

The length of major axis is 2a = 10 => a = 10/2 = 5 => a = 5

The equation of the ellipse is:

x²/a² + y²/b² = 1  or b²x² + a²y² = a²b²

When we replace value of a and b we get:

x²/5² + y²/3² = 1  or 3²x² + 5²y² = 5² · 3²    and finally

x²/25 + y²/9 = 1  or 9x² + 25y² = 225

God with you!!!
