6. What are the solutions for p2 - 16 = 0 ?<br> A) {-4,4} B) {4}<br> C) {-8, 8} D) {8}

AVprozaik [17]

Answer:

Step-by-step explanation:

Given

p² - 16 = 0 ( add 16 to both sides )

p² = 16 ( take the square root of both sides )

p = ± $\sqrt{16}$ = ± 4

Thus solution is { - 4, 4 } → A

How do I solve this using the Pythagorean theorem and leaving it in radical form ?

scoray [572]

If the legs of a right triangle are a and b and the hypotnuse is c then
a²+b²=c²

so we are given
the legs are x and √7
and the hypotnuse is √19
so

x²+(√7)²=(√19)²
x²+7=19
minus 7 both sides
x²=12
sqrt both sides
x=√12
x=√(4*3)
x=(√4)(√3)
x=2√3
