Answer:

(47+37)(47-37)

Step-by-step explanation:

47^2-37^2 is a difference of two squares. a^2-b^2 = (a+b)(a-b) so this expression can be factored to (47+37)(47-37) = (84)(10) = 840

klasskru [66]

Answer:

<em>n= Total number of packages on trucks= 6096</em>

<em>n = T x P (Model Equation)</em>

Step-by-step explanation:

No. Of delivery trucks = T = 127

Package on each truck = P = 48

Total number of packages on trucks =n= ?

Each truck contains 48 packages and total trucks were 127, to find total number of packages on trucks , we just need to multiply the number of trucks with the number of package on each truck.

Total number of packages on trucks =n= (No. Of delivery trucks) x (Package on each truck)

n = T x P (Model Equation)

n= 127 x 48

n= 6096 (Total number of packages on trucks)

Answer:

9. x = 7

10. x = 12

9x - 3 = 7x + 11

2x = 14

x = 7

10. The alternate interior angles are congruent.

5x - 20 = 2x + 16

3x = 36

x = 12

Finger [1]

Answer:

D

Step-by-step explanation:

for A if you subtract 3 from both sides and divide by 10 from both you get x = 0 so that has infinate solutions

for B you add 8 to both sides and divide by 16 getting the same thiong as A

For C you ditribut 4 to 2x and -3 getting 8x-12=8x-12 if you solve it you get the answer as A & B

For D if you subtract 12 from one side you get -6x = -6x -12 (-12)

causing you not to be able to solve it
