Answer:

Step-by-step explanation:

n(AUB)=n(A)+n(B)-n(A∩B)

n(A∪B)=80+65-65=80

so least value of n(A∪B)=80

Answer:

Step-by-step explanation:

first we are told that side and ae and a f are the same

so that means one side of each triangle is the same

next we are told that that the lines coming off of those sides are both right angles. so we know these are both right triangles

and b/c both of those angle are right angles... the sides ab and ac have to also be the same length.. or the angle could not be a right angle

therefore since two sides are the same length then all 3 must be the same lengths

and b/c all three are the same these two triangles are the same .. congruent

Jake is comparing the prices of two laundry service companies. Company A charges $20 per load and an additional $8 as service ch
svet-max [94.6K]
X = number of loads
company A : 20x + 8
company B : 24x + 4

20x + 8 = 20(5) + 8 = 100 + 8 = 108 (company A)
24x + 4 = 24(5) + 4 = 120 + 4 = 124 (company B)
company A charges less

20x + 8 = 20(9) + 8 = 188
24x + 4 = 24(9) + 4 = 220
220 - 188 = $ 32 bucks is saved by using company A
