Q1.) Tegan needs to make 68 more snow blocks to finish building an igloo. Write an equation for the number of blocks Tegan still needs to make, m, when she has completed c blocks.
Tegan completes 33 blocks.
Q2.) How many blocks does Tegan still need to make to finish the igloo?

answer: a.   one is a factor of every whole number since every number is divisible by itself.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
