4 x 7 is 28, and 8 x 7 is 56. You can use 4 x 7 to find 8 x 7 by multiplying that first and doubling that quotient.
Half of 56 is 28, therefore doubling that allows us to find the quotient of 8 x 7.
Answer:
a) This is not an exponential function because the variable is in the exponent position.
c) The base is 4 not 2.
Step-by-step explanation:
The given function is 
........... (1)
a) This is not an exponential function because the variable is in the exponent position.
c) The base is 4 not 2.
The general form of an exponential function is given by 
, where A is the initial value of the function and B is the base. (Answer)

Answer:
12.5
Step-by-step explanation:
.25 x 50= 12.5
Factor out the common term; 3
(3(x + 1))^2 = 36
Use the Multiplication Distributive Property; (xy)^a = x^ay^a
3^2(x + 1)^2 = 36
Simplify 3^2 to 9
9(x + 1)^2 = 36
Divide both sides by 9
(x + 1)^2 = 36/9
Simplify 36/9 to 4
(x + 1)^2 = 4
Take the square root of both sides
x + 1 = √4
Since 2 * 2 = 4, the square root of 2 is 2
x + 1 = 2
Break down the problem into these 2 equations
x + 1 = 2
x + 1 = -2
Solve the first equation; x + 1 = 2
x = 1
Solve the second equation; x + 1 = -2
x = -3
Collect all solutions;
<u>x = 1, -3</u>
