Expanding the given expressions using Foil:
1)(–7x + 4)(–7x + 4) =
2) (–7x + 4)(4 – 7x)=
3)(–7x + 4)(–7x – 4)=
=
4)(–7x + 4)(7x – 4)=
The third option that is (–7x + 4)(–7x – 4) is difference of two squares.
The one you have highlighted is correct
The problem with the question is that 51% of 1009 adults could not have said that their biggest fear was losing vision. The issue with 51% of 1009 is that you wont be left with a whole number, but a decimal instead. You cant have a decimal of a person.
The formula to find the volume of a cylinder is v= hㅠr*2, so you can sub the measurements into the formula.
V = (6)ㅠ(2)*2
V = 6ㅠ4
V= 75.4 (approx)
Hi there!
Since the sum of all angles in any triangle always adds up to 180 degrees, we can calculate this and solve for x.
4x + x + x = 180°
6x = 180
180 ÷ 6 = x
x = 30
So, now we know that x is 30°.
Hope this helps!
