Answer:
a) 6x³ − 5x² − 39x + 35
b) no
Step-by-step explanation:
(2x − 5) (3x² + 5x − 7)
Distribute:
3x² (2x − 5) + 5x (2x − 5) − 7 (2x − 5)
Distribute again:
6x³ − 15x² + 10x² − 25x − 14x + 35
Combine like terms:
6x³ − 5x² − 39x + 35
5x − 2 is the opposite of 2x − 5, so you would get the negative of the answer from part (a).
-9+_=-2
+9 both sides
_= 7
Answer: It will cost him $237 to seed the entire backyard
Step-by-step explanation:
Hi, to answer this question, first, we have to calculate the area of the rectangular backyard:
Area of a rectangle = length x width
Replacing with the values given:
A = 20 x 15 = 300 ft2
Since seed cost 0.79 per square foot, we simply have to multiply that price by the area:
0.79 x 300 = $237
It will cost him $237 to seed the entire backyard
