Answer:
31
Step-by-step explanation:
Given
x² + 5x - 3 = 0
with a = 1, b = 5, c= - 3 , then
sum of roots x₁ + x₂ = -
= -
= - 5
product of roots =
=
= - 3
Now
(x₁ + x₂)² = x₁² + 2x₁x₂ + x₂² , that is
(- 5)² = x₁² + 2(- 3) + x₂²
25 = x₁² - 6 + x₂² ( add 6 to both sides ), then
x₁² + x₂² = 31
Answer:
Step-by-step explanation:
Neptune is about 2,700,000,000 miles from Earth.
Mercury is about 135,000,000 miles from Earth.
A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. The power is the number of decimal places you move.
1) 2,700,000,000 = 2.7 x 
135,000,000 = 1.35 x 
2)
You can see there is only one extra 0 on top, the rest will cancel so you have:
It's 20x farther to Neptune from Earth, than it is to Mercury from Earth.
Answer:
104 Pages
Step-by-step explanation:
on Monday she reads 3/8 of the novel which means
x 352 = 132 pages
on Tuesday she reads 28 pages, doesn't require any calculations.
on Wednesday she reads 1/4 of the novel,
x 352 = 88
Just add all of that,
132+28+88=248 Pages
Subtract the novel pages by the read pages value
352-248=104pages.
