1. the temperature on a summer afternoon is 85°f. define a variable and write an
expression to find the temperature after it changes. then evaluate your
expression for a decrease of 11 degrees fahrenheit.
o
a 85 - c; 85 - (-11) = 96; 96°f
b 85+ c; 85+ (-11) = 74; 74°f
c 11 + c, 11 +(-85) = 96; 96°f
d 11 - c: 11 - (-85) = 74; 74°f

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
