Answer:

3/4

Step-by-step explanation:

To add fractions, they must have common denominators

convert them to common denominators

4/7 × 4/4 = 16/28

now their denominators are the same

16/28 + 5/28

add the numerators

16 + 5 = 21

21/28

Both the numerator and the denominator can be divided by 7

3/4 is the simplest form

A rectangular park had a perimeter of 18 miles. It is 7 miles wide. What is the area of the park?

4vir4ik [10]

Perimeter = 18 miles
Perimeter = 2a + 2b
2a + 2b = 18

a = ?
b = 7

18 = 2a + 2*7
18 = 2a + 14
2a = 18 - 14
2a = 4
a = 2

Area = a * b
Area = 2 * 7 = 14 miles2

Solve: (2x - 3)^2 = -4

Wewaii [24]

Answer:

No real solutions;

$x=i+1.5$

Step-by-step explanation:

The easiest method to solve an algebraic equation is to use inverse operations. This applies to the given equation;

$(2x-3)^2=-4\\$

- Take the square root of both sides

$\sqrt{}$

==================================================================

As one can see, the right side is a negative number. However, one cannot take the square root of a negative number and get a real result. Therefore, one must use imaginary numbers. Remember, the imaginary unit ( $i$ ) represents ( $\sqrt{-1}$ ).
