Answer:
A: (3x +4)
B: (4x +5y) × (4x -5y)
Step-by-step explanation:
<u>Part A</u>:
Since we know the trinomial is a perfect square, we know the terms of each binomial factor are the square roots of the first and last terms of the trinomial.
9x² +24x +16 = (√(9x²) +√16)² = (3x +4)²
The side of the square is 3x+4.
__
<u>Part B</u>:
The difference of squares is factored like this:
a²-b² = (a +b)(a -b)
The given area expression is the difference of squares with ...
a = 4x, b = 5y
so, the factorization is ...
16x² -25y² = (4x +5y)(4x -5y)
The dimensions of the rectangle are (4x+5y) by (4x-5y).

Answer:
( 1 , -3 ) for every +1 on the x line you go -3 on the y I hope this is what you need
Answer:
The intersection point of diagonals is (0.5,-4.5).
Step-by-step explanation:
The end points of first diagonal are p(-3, -2) and i(4, -7).
The end points of second diagonal are a(4, -2) and d(-3, -7).
If a line passing through two points, then the equation of line is
The equation of first diagonal is
.... (1)
The equation of second diagonal is
.... (2)
Add equation (1) and (2),
Put this value in (1).
The intersection point of diagonals is (0.5,-4.5).
Answer:
3 3/4 or 3.75 hours.
Step-by-step explanation:
If you need to travel 300 km, assuming you are going at the speed limit, you take the total amount and divide it by that.
300 / 80 = 3.75 hours
