Which situation cannot be represented by this equation? 3x+4=19? i will give brainliest. for the person who shows there work a) penny is selling candles for $3 each at a fund-raiser. if she starts selling with $4 to her make change, how many candles, x , will she have to sell to end up with $19? b) penny is selling candles for $4 each at a fund-raiser. if she starts selling with $3 to her make change, how many candles, x , will she have to sell to end up with $19 c) penny has already sold 3 candles at a fund-raiser. if she started selling with $4 to her make change, what is the price, x , of each candle, if she ends up with $19

Astudent was asked to find the square of 7x+3. the student quickly wrote (7x+3)^3= 49x^2+9. identify the student's error and provide the correct answer.

Farmers know that driving heavy equipment on wet soil compresses the soil and injures future crops. here are data on the "penetrability" of the same type of soil at two levels of compression. penetrability is a measure of how much resistance plant roots will meet when they try to grow through the soil. compressed soil 2.85 2.66 3 2.82 2.76 2.81 2.78 3.08 2.94 2.86 3.08 2.82 2.78 2.98 3.00 2.78 2.96 2.90 3.18 3.16 intermediate soil 3.17 3.37 3.1 3.40 3.38 3.14 3.18 3.26 2.96 3.02 3.54 3.36 3.18 3.12 3.86 2.92 3.46 3.44 3.62 4.26 use the data, omitting the high outlier, to give a 95% confidence interval for the decrease in penetrability of compressed soil relative to intermediate soil. compute degrees of freedom using the conservative method. interval: to

Point a is at 12, and point d is at 56. point c is midway between a and d, and point b is midway between a and c. which of these is the coordinate of b?
