Answer:
The picture has the answer
Step-by-step explanation:
<span> 53/2 ÷ 53/8
(53 × 8) / (53 × 2)
424/106
4/1
4
The answer is 4.

(See attached graphic).
Total = Principal * e ^ (rate * years)
Total = 12,000 * 2.718281828 ^ (.064 * 12)
Total = 12,000 * 2.718281828 ^ .768
Total =
12,000 * <span>

Answer:
Josh's solution is NOT correct.
Step-by-step explanation:
Josh's solution is NOT correct.
x^2 - 6x - 7 = 0
As you know:
-7 = (-7) * (+1) and -6 = (-7) + (+1) = -6
So factor x^2 - 6x - 7 = 0, you have
(x - 7)(x + 1) = 0
Set each factor = 0 to solve the equation
x - 7 = 0; x = 7
x + 1 = 0; x = -1
Solutions: x = -1 and x = 7
So Josh's solution is NOT correct.
Answer:
84cm^2
Step-by-step explanation:
P=2l+2w
We are given,
P=40cm
l=2w+2
Plug these into the first formula and solve for the dimensions,
length and width, of the rectangle:
40=2(2w+2)+2w Simplify
40=4w+4+2w
40=6w+4
36=6w
6=w OR the width is 6cm, therefore,
the length is
l=2(6)+2
l=14cm
To calculate the area of a rectangle, A=lw,
plug the length,14cm, and the width, 6cm, into this formula
A=(14)(6)
A=84cm2 OR the area of the rectangle is 84cm^2
