Step-by-step explanation:
x^2n + 10x^n + 16
= (x^n)(x^n) + 10(x^n) + 16
= (x^n + 2)(x^n + 8).
<h3>
Answer:</h3>
90°
<h3>
Step-by-step explanation:</h3>
The polygon has 7 sides, so the total of internal angles will be ...
... 180°×(7 -2) = 900°
The sum is then ...
... x + 146° +122° +142° +140° +110° +142° = 900°
... x + 802° = 900° . . . . . simplify
... x = 98° . . . . . . . . . . . . .subtract 802°

<em>Comment on angle measure formula</em>
The usual formula for computing the total of internal angles of a convex polygon with n sides is ...
... total angle measure = (n -2)×180°
This can be simplified from the fact that the sum of external angles is always 360°. That is, for internal angles a1, a2, ..., an, the sum of external angles is ...
... (180° -a1) +(180° -a2) +... +(180° -an) = 360°
... n×180° -(a1 +a2 +... +an) = 360° . . . . . . collect terms
... n×180° -360° = (a1 +a2 +... +an) . . . . . . add ∑ak -360°
... 180°×(n -2) = a1 +a2 +... +an . . . . . . . . . factor out 180°
Answer:
the answer is:
Basic Of Algebra. Basics of Algebra cover the simple operation of mathematics like addition, subtraction, multiplication, and division involving both constant as well as variables. For example, x+10 = 0. This introduces an important algebraic concept known as equations.
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Slope m = 2
The point is (0,3)
x1 = 0 and y1 = 3
And y - y1 = m(x - x1)
y - 3 = 2(x - 0)
y - 3 = 2x
y = 2x + 3 this is the equation
Answer:
Solving the inequality 
we get 
Option D is correct option.
Step-by-step explanation:
We need to solve the inequality and find value of x
Solving the inequality for finding value of x, we will keep x on left side of inequality and all other terms on the right side.
Adding 2 on both sides
Now, we will divide 3 on both sides
So, we get x < 2
Solving the inequality we get
Option D is correct option.
