360 degrees in circle
70/360 of full circle=7square feet
7/36 of full circle=7 squre feet
times both sides by 36/7
full circle=36 square feet

area=pir^2
36=pir^2
divide oth sides by pi (use 3.141592)
11.459=r^2
sqrt both sides
3.3851

1) 26 = 8 + v 2) 3 + p = 8
aleksklad [387]

Answer:

268+v2)3+p=8     =p=−3v2−796

Step-by-step explanation:

Let's solve for p.

(268+v2)(3)+p=8

Step 1: Add -804 to both sides.

3v2+p+804+−804=8+−804

3v2+p=−796

Step 2: Add -3v^2 to both sides.

3v2+p+−3v2=−796+−3v2

p=−3v2−796

Area of the entire rectangle =x^2+10x+24

Solution:

Area of the blue box =  length × width

                                  =x\times x

Area of the blue box =x^2

Area of the pink box =  length × width

                                  =4\times x

Area of the pink box =4x

Area of the green box = length × width

                                     =6\times x

Area of the green box =6x

Area of the orange box = length × width

                                       =6\times 4

Area of the orange box = 24

Total area of the rectangle =x^2+4x+6x+24

                                             =x^2+10x+24

Area of the entire rectangle =x^2+10x+24

What is that product of 2x + y and 5x -y + 3
poizon [28]

Answer:

10x² + 6x + 3xy + 3y - y²

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, as shown

(2x + y)(5x - y + 3)

= 2x(5x - y + 3) + y(5x - y + 3) ← distributing

= 10x² - 2xy + 6x + 5xy - y² + 3y ( collect like terms )

= 10x² + 6x + 3xy + 3y - y²
