(2x + 3) • (x + 3)
2x • x = 2x^2
2x • 3 = 6x
3 • x = 3x
3 • 3 = 9
6x and 3x combine to get 9x, which when all written out is equal to your original trinomial.
Answer:
225 inches²
Step-by-step explanation:
Let the length be l and width be w
Condition 1
2l+2w=68 (Perimeter=68)--------(i)
Condition 2
l=3w-2 ---------(ii)
Putting equation (ii) in (i)
2(3w-2)+2w=68
6w-4+2w=68
8w-4=68
8w=68+4
8w=72
dividing both sides by 8
w=9 inches
now putting w=9 in (ii)
l=3(9)-2
l=27-2
l=25 inches
Now
Area of rectangle = l × w
=9 × 25
=225 inches²
Answer:
y-3 = 4(x+2) point slope form
y = 4x+11 slope intercept form
Step-by-step explanation:
Since we have a point and a slope, we will start with point slope form
y-y1 = m(x-x1)
y-3 = 4(x--2)
y-3 = 4(x+2)
This is point slope form
Distribute
y-3 = 4x+8
Add 3 to each side
y-3+3 = 4x+8+3
y = 4x+11
slope intercept form
