Answer:the answer is D.
Step-by-step explanation:
5(x)- -3(y) is 8. Make the negative into a positive if the equation looks like that. 4x5=20 + 3x-3=-9 so 20+-9= 11
If a farm contains 1250 trees, and each tree produces 160 mangoes, the farm produces
This means that 
farms produce 
mangoes.
If you want 1 million mangoes, you must solve the equation
So, you need 5 farms.
Answer:
2(x -1) - 3(4 x² + 7 x +1)
(-16 x² +10 x - 3) + (4 x² -29 x -2) these expressions are equivalent to the polynomial -12 r²- 19 r -5
Step-by-step explanation:
2(x -1) - 3(4 x² + 7 x +1)
= 2 x -2 -12 x² - 21 x - 3
= -12 x² -19 x -5
This expression is equivalent to the polynomial -12 r² - 19 r -5
Another equation is
(-16 x² +10 x - 3) + (4 x² -29 x -2)
= -16 x² +10 x - 3 + 4 x² - 29 x - 2
= -12 x² -19 x - 5
This expression is also equivalent to the polynomial -12 r² - 19 r -5
notice, just like in any multiplication, you can simply multiply each term of either polynomial times the other, sum them up and then cancel like-terms.
