Answer:
The area of the shape after it has been enlarged by
scale factor 2 will be: 10 cm²
Step-by-step explanation:
The Area is basically a measure of how much space in square units there is inside an object.
As the shape is shown on the centimeter grid.
- The shape clearly occupies the space of 5-centimeter squares.
We also know that If the scale factor > 1, the image is enlarged.
As we know to determine the area of the shape after it has been enlarged by scale factor 2, all we need to do is to multiply the area of the original shape by 2.
The area of original shape = 5 cm²
The area of the shape after the dilation by a scale factor 2 = 5 × 2 = 10 cm²
Thus, the area of the shape after it has been enlarged by
scale factor 2 will be: 10 cm²
23/10,000 after your decimal is tenths, next is hundredths then thoundths finally ten thoundths good luck

B is your answer
Step-by-step explanation:
(50.40 + 309.60) divided by 144 = 2.50
Answer:
y = - 2x - 3
Step-by-step explanation:
We know: y=ax^2+bx+c
Given: (2, 5), (3, 12), and (-1, -4)
so...
We plug in these numbers:
5 = a*(2^2) + b*2 + c
12 = a*(3^2) + b*3 + c
-4 = a*((-1)^2) + b*(-1) + c
simplify:
5 = 4a + 2b + c
12 = 9a + 3b + c
-4 = a - b + c
Solve this 3 variable system
Combine 5 = 4a + 2b + c and -4 = a - b + c
-8 = 2a - 2b + 2c from multiplying the equation -4 = a - b + c by 2
5 - 8 = 4a + 2a + 2b - 2b + c + 2c
-3 = 6a + 3c
-1 = 2a + c
next multiply -4 = a - b + c by 3
-12 = 3a - 3b + 3c add to 12 = 9a + 3b + c
-12 + 12 = 3a + 9a + -3b + 3b + 3c + c
0 = 12a + 4c
0 = 3a + c
combine -1 = 2a + c and 0 = 3a + c
1 = -2a - c
0 + 1 = 3a - 2a + c - c
1 = a
so... -1 = 2*1 + c
-1 = 2 + c
c = -1 -2 = -3
use equation -4 = a - b + c , solve for b
-4 = 1 - b + (-3)
-4 = -2 - b
b = -2 + 4 = -2
so a = 1, b = -2, c = -3
y = x^2 - 2x - 3
y = - 2x - 3
Answer:
the answer is 1.4809 because you count 4 numbers after the decimal place and the fifth number influences the fourth. remember, if its 4 or below you round down and if its 5 or higher you round up.
