hope this helps!
Step-by-step explanation:
A = {-1, 2, 3}
B = {1,2}
AxA = {(-1,-1) (-1,2) (-1,3) (2,-1) (2,2) (2,3) (3,-1) (3,2) (3,3)}
BxB = {(1,1) (1,2) (2,1) (2,2)}
Answer:
254 
Step-by-step explanation:
Surface Area = 2Lh+2Lw+2wh
L=4 cm
h=9 cm
w=7 cm
Surface Area = 2(4)(9)+2(4)(7)+2(7)(9)
Surface Area = (72+ 56 +126)
Surface Area = (72+ 56 +126)
Surface Area =254
Answer:
Step-by-step explanation:
Circumference = 2pi r
440 = 2 *22\7 *r
70 = r
Area= pi r^2
Area= 22\7 *70*70
Area =15400
If they have no other common factors other than one, the LCM is equal to the product of the two numbers.
For example, the factors of 3 are 3 and 1 and the factors of 10 are 1, 2, 5, and 10. Since they share no common factors other than one, the LCM is equal to 3*10= 30.
D. Distributive because 5 is distributed to (x-3) to get 5x-15
