Answer:
3(4) + 5
Step-by-step explanation:
Use BIDMAS (Brackets, indicies, division, multiplication, addition, subtraction.)
88= 2l + 2w
l=3w
88=2(3w)+2w
88= 6w+2w
88=8w
w=11
l=3(11)
l=33
width= 11
length= 33
15=pants
d less than pants means
15-d
5 of them
5(15-d)=cost of shirts
so total cost=15+5(15-d)
An equation can be determined as linear if it is first order in a single variable, i.e. y=3x, but not y=3x^2.
A graph will be linear if the slope is constant
