The area of his garden used for for growing roses is 144m^2
-The polynomial has 5 terms.
-The leading coefficient is -2.
-The degree of the polynomial is 7.
-The constant term is 4.
Step-by-step explanation:
A polynomial is an expression which has many terms. Each term is separated by addition or subtraction. The standard form of a polynomial is and is written in descending order by exponent. The highest exponent is known as the degree of the polynomial. The leading term at the beginning has a leading coefficient.
Using the information above, select what applies for -2xy^5+3x^7-10x^3y^6+8x^6+4.
-The polynomial has 5 terms.
-The leading coefficient is -2.
-The degree of the polynomial is 7.
-The constant term is 4.
-The polynomial is in decreasing degree order.

It´s length is 10.5 because:
Perimeter = (2 x width) + (2 x length), so the equation is:
Length = [Perimeter - (2 x width)] / 2
Answer:
x = 7/2 ±sqrt(65)/ 2
Step-by-step explanation:
x^2=7x+4
Subtract 7x from each side
x^2-7x=7x-7x+4
x^2 -7x =4
Complete the square
Take the coefficient of x and divide by 2
-7/2
Then square it
(-7/2)^2 = 49/4
Add this to each side
x^2 -7x +49/4 =4+49/4
(x-7/2)^2 = 4 +49/4
(x-7/2)^2 = 16/4 +49/4
(x-7/2)^2 =65/4
Take the square root of each side
sqrt((x-7/2)^2) =±sqrt(65/4)
x-7/2 = ±sqrt(65)/ sqrt(4)
x-7/2 = ±sqrt(65)/ 2
Add 7/2 to each side
x-7/2 +7/2=7/2 ±sqrt(65)/ 2
x = 7/2 ±sqrt(65)/ 2
