Answer:
Step-by-step explanation:
Triangle A
Use Pythagorean theorem.
x² + 12² = 13²
x² + 144 = 169
x² = 169 - 144
x² = 25
x = √25
x = 5 cm
Triangle B:
y² = 12² + 5²
= 144+ 25
= 169
y = √169
y = 13
Your answer is 157.50.
Principal: $450
Rate: 5%(0.05)
Time: 5(years)
450*0.05*7=157.5

We're multiplying two monomials. Multiplying the numerical values first, (-4)(2), would give us -8. To multiply the s values, (s)(s</span>³), we just have to add the exponents. Keep in mind that
. Adding the exponents of the variable s gives us
. Our answer is
