Answer:

Equation: 3(x+5)=60

Solution: 15 inches

Step-by-step explanation:

Let x represent the original side length of the equilateral triangle. Then, the new length of each side is x+5. Because a triangle has three sides, the new perimeter is 3(x+5), which is 60 inches. Dividing both sides by 3, we get that x+5=20, so x=15.

Are all real numbers and imaginary numbers also complex numbers? Explain, using the parts of a complex number.
horsena [70]
Numbrs are divided in real and imaginary, so they can't be together one thing
Complex number are imaginary numbers

in the other hand if you multiply am complex by i than you get a real number, but that is just a way of expressing, so not all numbers are complex.

(5i)²=-25----- a real number is a product of 2 imaginary but it doesn't mean that we can say all are complex

(the explaination is subjectiv, based just in my opinion and knowlige hope it helps)
