Answer:
4x^4y + 20x^2y^2 - 28x^3y
Step-by-step explanation:
4xy(x^3 + 5xy - 7x^2)
= 4xyx^3 + 4xy * 5xy - 4xy * 7x^2
= 4x^2y + 4xy * 5xy - 4xy * 7x^2
= 4x^4y + 20x^2y^2 - 4xy * 7x^2
= 4x^4y + 20x^2y^2 - 28x^3y
Answer: -4.3 feet
or -5.4 ft + 1.1 ft
Step-by-step explanation:
How I solved this is by reading this carefully , It said 1.1 feet above water so positive and -5.4 feet dive down so that is negative correct? so you would subtract - 5.4 + 1.1 which is -4.3
Am I correct?
It's the second option, because the signs are facing each other & it's underlined. That's why the circles are shaded in, the inequality means the numbers between -4 & 3 are what is needed. Hope that helps
