Answer:
Simplifying
3k(k + 10) = 0
Reorder the terms:
3k(10 + k) = 0
(10 * 3k + k * 3k) = 0
(30k + 3k2) = 0
Solving
30k + 3k2 = 0
Solving for variable 'k'.
Factor out the Greatest Common Factor (GCF), '3k'.
3k(10 + k) = 0
Ignore the factor 3.
Subproblem 1
Set the factor 'k' equal to zero and attempt to solve:
Simplifying
k = 0
Solving
k = 0
Move all terms containing k to the left, all other terms to the right.
Simplifying
k = 0
Subproblem 2
Set the factor '(10 + k)' equal to zero and attempt to solve:
Simplifying
10 + k = 0
Solving
10 + k = 0
Move all terms containing k to the left, all other terms to the right.
Add '-10' to each side of the equation.
10 + -10 + k = 0 + -10
Combine like terms: 10 + -10 = 0
0 + k = 0 + -10
k = 0 + -10
Combine like terms: 0 + -10 = -10
k = -10
Simplifying
k = -10
Answer:
100
Step-by-step explanation:
Since, line a is parallel to line t ( from diagram ).
x - 30 and 70 are alternate interior angles.
Reason : -
Alternate interior angles are equal when two lines are parallel and cut by a transversal line.
x - 30 = 70
x = 70 + 30
x = 100
Answer:
X=84/21
Step-by-step explanation:
X/14=6/21
X=(6/21)(14/1)
X=84/21
Answer:
Step-by-step explanation:
One approach would be to begin the indicated multiplication: Multiply a² by a, obtaining a³, which is the first term of the product a3 – a2b + ab2 + a2b – ab2 + b3. Please use " ^ " to indicate exponentiation, or (²) or (³):
a(a² - ab + b²) = a³ (plus 2 more terms, which are -a²b and ab²).
Here we are applying the distributive property of multiplication.
Answer:
They are not similar
Step-by-step explanation:
Angles dont match
