Center square = 12 x 12 ft²

Area of a triangle = 1/2 b h       there are four of them     4     * 1/2 (12)(9)             add the reds for final answer

Given   p + 3d = 14.75

            2p + 5d = 26            Muliply the top equation by -2 to get:

           -2p -6d   = -29.50     now add the two bottom equations

                   - d = - 3.50

                     d = 3.50             use this value of  'd' in one of the equations to calculate 'p'

y = 1/2 ( 152+64)  = 108

then   xyz = 180 - 108 = 72 ^o

Volume of base =  8 x 5 x 4  cm³

Volume of pyrimad top   = 1/3   l w h

                = 1/3  ( 8)(4)(6)    cm^{3                            add the REDs}  

(5x+2)²  - 14        take it from here   

AVERAGE price = $ 8000

then    7 x $8000 = $ 56000.00

f(x) = 2(1.1)*, where x is the time in weeks.     something is missing in your equation....

f(x) = 2 + (1.1)*x   Perhaps?

initially x = 0   and the ivy is 2 mt tall

2+ 1.1 x     when x = 10     is  13 m

c,)   10m  = 2 + 1.1 x      x = 8.2 weeks

Find height with pythagorean theorem

 Sqrt (20^2 - 10^2= sqrt 300

area of trainagle  = 1/2 b * h

                            = 1/2 10 * sqrt 300

and multiply by the 'depth' of 16 ft to find the volume

   1/2 * 10 * sqrt300 * 16 = 1385.64 ft3

a =  180 - 36

b = 180 - 113

(2, -2)   the same as   90 degrees clockwise
