Duval County landscaping uses 2 different sized trucks to deliver mulch the 1st truck can transport executive yards of mulch and the 2nd can transport Y cubic yards of moach the 1st truck makes 12 trips to a job site while the 2nd mixed 14 trips create an expression that represents the difference in the total number of cubic yards that the 1st truck delivers compared to the 2nd

the answer is c hope it

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
