The sun has cast a shadow for the tree and the water geyser in the park. The rangers need the height of the tree given the measurements for the geyser, its shadow, and the tree's shadow. Write and solve a proportion using the ratio LaTeX: \frac{height}{shadow}h e i g h t s h a d o w to find the height of the tree.

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

step-by-step explanation:

hello! just here for points! though i wish i knew!

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
