The diameter of Jupiter is about 40 times the diameter of Earth's moon.
For the first question, use slip and slide or the box method to get (x-2)(2x-3)
Do the same for the second question to get (3x-4)(x+1)
They are both right triangles so we can use the Pythagorean
theorem to solve.
6. B = sqrt(15^2-9^2)
B = 12 mm
7. B = sqrt(26^2-10^2)
B = 24 Cm
We need to get rid of expression parentheses.
If there is a negative sign in front of it,
each term within the expression changes sign.
Otherwise, the expression remains unchanged.
Numerical 'like' terms will be added. There is only one group of like terms
the answer is: ab-4a-5
