Answer:
F(2b-1) = 4b² - 6b + 4
Step-by-step explanation:
Replace all the x with 2b-1
F(x) = x² - 2x + 4
F(2b-1) = (2b-1)² - 2(b) + 4
= 4b² - 4b + 1 - 2b + 4
= 4b² - 6b + 4
Answer:
the answer is y=8x+42
Step-by-step explanation:
y-y=m(x-x¹)
y-2=8(x-(-5))
y-2=8x+40
+2 +2
y=8x+42
Lets say we have 7 items, and we add 7 more.
Then, in the next situation, we have 7 items and we add 8 more. Now we know that 8 = 7 + 1, so we are actually performing 7 + 7 +1. Our diagram already shows us the value of 7 + 7 so we just add 1.
The items can be represented by circles, triangles etc
Hello!
You can separate the shape into two rectangular prisms
prism 1 - 9, 2 ,4
prism 2 - 4, 2, 8
Since the frosting is on the outside of the cake you have to find the surface area
To find the surface area you use the equation
2(wl + hl + hw)
Put in the values you know
2(9 * 2 + 4 * 2 + 9 * 4)
multiply
2(18 + 8 + 36)
Add
2(62) = 124
Now you find the surface area of the second prism
2(4 * 2 + 2 * 8 + 4 * 8)
Multiply
2( 8 + 16 + 32)
Add
2(56) = 112
Now add the two surface areas to get the surface area of the whole shape
112 + 124 = 236
The answer is 236in squared
Hope this helps!
