Answer:
x^3 <-- exponent, x to the power of three
Explanation:
x(x+2)(x+4)
=(x(x+2))(x+4)
=(x(x+2))(x)+(x(x+2))(4)
=x^3+2x^2+4x^2+8x
=x^3+6x^2+8x
Answer:
It will take 15 years for $500 to yield $900 at an interest rate of 0.12
Step-by-step explanation:
Simple Interest equals Principal times Rate times The time in years,
That is SI = P*R*T
SI is $900
P = $500
R = 0.12
T i.e. Time is unknown
T will be equal to SI divided by P*R
i.e., T = SI/PR
T = $900/$500*0.12 = 900/60
T = 15 years.
Therefore, it will take $500 investment to yield $900 interest in 15 years at an interest rate of 0.12
Answer:
Step 2; it should be m∠w + m∠z = 180 degrees (supplementary angles)
Step-by-step explanation:
Step 1: m∠x + m∠y + m∠z = 180 degrees (sum of angles of a triangle)
Step 2: m∠w − m∠z = 90 degrees (corresponding angles)
We are adding the angles to form a straight line which is 180 degrees
Step 3: Therefore, m∠x + m∠y + m∠z = m∠w + m∠z
Step 4: So, m∠x + m∠y = m∠w
Answer:
As we know, if we add up the interior and exterior angles of one corner of a triangle, we always get 180. the exterior angle in question is equal to the sum of the other two angles in the triangle
