Answer:
(V+3)(V+2)
Step-by-step explanation:
Draw a line on the hole which forms a square. The square lengths are 3 inches because 12-9 equals 3. 3^2= 9 which is the area of that square below the rectangle. Draw another line to separate the big rectangle into two rectangles. The smaller of these two new rectangles dimensions are 4 by 7 in. 7x4= 28 ft as the area of the smaller rectangle. The dimensions are the larger rectangle are 4 by 9 inch. The area of the larger rectangle is 36 inches.
36+28+9=73 in^2 as the total area.
Well the vertex is the highest or possibly lowest point in a quadratic equation, the part where it hits the curve. For example imagine this is your graph--> ∩.
This graph has its vertex at the top. So when we complete the square and find the zeroes we can then find where the graph meets in the middle thus finding our vertex.
-138 <span>≥ -6(6b - 7)
Start by multiplying everything within the parentheses by -6.
-138 </span><span>≥ -36b + 42
Now move the +42 to the other side, so you're left with -36b. (You do this by subtracting 4242)
-138 - 42 </span><span>≥ -36b
-180 </span>≥ -36b
Divide both sides by -36 to find the value of b.
-180 / -36 ≥ b
5 ≥ b.
The answer is b ≤ 5.
Answer:
2
Step-by-step explanation:
2x+2=8
-2. -2
2x = 6
Divide by 2 on both sides
6/3
x=2
