Do 77 times 14
770+308=1,078
Divide 1,078 by 100
=10.78
A² + 4a + 3
(a+3)(a+1) This is the length and the width of the rectangle.
Perimeter = length + length + width + width
P = (a+3) + (a+3) + (a+1) + (a+1)
P = a + a + a + a + 3 + 3 + 1 + 1
P = 4a + 6 + 2
P = 4a + 8
B) 4a + 8
Answer:
15-4x
Step-by-step explanation:
15 fewer is hinting at subtraction and then it states what we are subtracting 15 from which is the product of 4 and some number (4x).
Answer:The starting value is 20,300, and the value is decreasing by 9.5% each year.
Because it decreases by 9.5% each year based on the previous amount, we use an exponential decay model.
A decrease by 9.5% corresponds to multiplying by 91.5% each year.
We write . We plug in 11 years for t.
