<h3>
Answer: B) 6</h3>
===========================================================
Explanation:
x = original side length
2x = double the side length
The old area is x^2. The new square area is (2x)^2 = 4x^2
new area = (old area) + 27
4x^2 = x^2 + 27
4x^2-x^2 = 27
3x^2 = 27
x^2 = 27/3
x^2 = 9
x = sqrt(9)
x = 3
The old original square has a side length of 3 units.
The new larger square has a side length of 2x = 2*3 = 6 units which is the final answer (choice B)
old area = 3^2 = 9
new area = 6^2 = 36
The jump from 9 to 36 is +27 to help confirm the answer.
<span>If the equation of a line has a slope of 2 and passes through the point (1,3), which form would be used to write the equation of the line?
You should use the </span><span>Point- slope form because
</span><span>Point- slope form: (y - y1) = m( x - x1)
m = 2 and </span>passes through the point (1,3)
equation
(y - 3) = 2(x - 1)

Answer:
No The correct Answer is "G"
Step-by-step explanation:
First lets find 300% as a number which is 3 ok so now
increase 10 by 300%
so 100%+300%=400%
and half of 400 which is 200%
so H is no correct g is
Answer: 3 : 21 3/4
Because it is a enlargement of 3, you need to multiply each side by 3 times.
We know that
for
y=a(x-h)^2+k
vertex is (h,k)
given vertex is (3,5)
y=a(x-3)^2+5
we are also given
(5,-3)
x=5 and y=-3 is a possible solution
-3=a(5-3)^2+5
-3=a(2)^2+5
minus 5 both sides
-8=a(4)
-8=4a
divide by 4 both sides
-2=a
the equation is
