Which is the best summary of the selection? Leaves are something to be thankful for because they produce carbohydrates.

Leaves conduct photosynthesis, which converts energy from the Sun into chemical energy that is useful and important to humans.

Photosynthesis is a vital part of the food chain.

Radiant energy is the most important part of photosynthesis. It is energy from the Sun, which leaves are thankful for.

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.

96 39 cause 135 -96=39 im smart (i used a calculater)

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
