d=8.1
1.2+d+0.4=9.7
Add 0.4 and 1.2
1.6+d=9.7
-1.6 -1.6
Subtract 1.6 from both sides
d=8.1
Answer:
6
Step-by-step explanation:
Given that the coordinate plane, three of the vertices of the rectangle are located at (-1.25, -0.25),
(-1.25, 0.25), and (1.25, 0.25)
The length L of the shape will be:
L = 0.25 - ( - 0.25 )
L = 0.25 + 0.25
L = 0.5
The width of the shape will be:
W = 1.25 - ( - 1.25)
W = 1.25 + 1.25
W = 2.5
Perimeter P = 2L + 2W
Substitute the Length and the width into the formula
P = 2(0.5) + 2(2.5)
P = 1 + 5
P = 6 metres
Therefore, the perimeter of the shape is 6 metres
Answer:
It should be
.

![300=3*10^{2}\\500=5*10^{2}\\\\300*500=(3*10^{2})*(5*10^{2})=(3*5)*10^{(2+2)}=15*10^{4}=1.5*10^{5}](https://tex.z-dn.net/?f=300%3D3%2A10%5E%7B2%7D%5C%5C500%3D5%2A10%5E%7B2%7D%5C%5C%5C%5C300%2A500%3D%283%2A10%5E%7B2%7D%29%2A%285%2A10%5E%7B2%7D%29%3D%283%2A5%29%2A10%5E%7B%282%2B2%29%7D%3D15%2A10%5E%7B4%7D%3D1.5%2A10%5E%7B5%7D)
Hello!
For this you can plug in the x values in the choices and see if you get the y value
y =
![-4^{3} - (-4)](https://tex.z-dn.net/?f=%20-4%5E%7B3%7D%20%20-%20%28-4%29)
-4^3 is -64
when you subtract a negative you are just adding
-64 + 4 = 60
Then you do the second one
![y = -3^{3} - (-3)](https://tex.z-dn.net/?f=y%20%3D%20%20-3%5E%7B3%7D%20%20-%20%28-3%29)
-3^3 is -27
-27 + 3 is -24
Then the third one
![y = -2^{3} - (-2)](https://tex.z-dn.net/?f=y%20%3D%20%20-2%5E%7B3%7D%20%20-%20%28-2%29)
-2^3 is -8
-8 + 2 is -6
Then the last one
![y = -1^{3} - (-1)](https://tex.z-dn.net/?f=y%20%3D%20%20-1%5E%7B3%7D%20%20-%20%28-1%29)
-1^3 is -1
-1 + 1 = 0
Since we did not get -2 the answer is D
Hope this Helps!
