Step-by-step explanation:
so in this case numerator can cancel the denominators and 7(d) and 14(n) can cancel also 6(n) and 18(d) when u do this u will get 2/3. u can decide to change to demical
Option (A) "A polygon has 7 sides. No angles go inside of the shape" is correct.
<h3>What is a regular polygon?</h3>
A polygon is a geometric figure with a finite number of sides in two dimensions. On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.
As we know, a convex heptagon is a polygon with seven sides, seven internal angles, and seven vertices, which means that a convex heptagon has seven sides.
A convex heptagon is a polygon that has 7 sides. No angles go inside of the shape.
Thus, option (A) "A polygon has 7 sides. No angles go inside of the shape" is correct.

Answer:
Step-by-step explanation:
Let's call B at the base of the triangle and call h at the height of the triangle. Then we know that:
The height of a triangle is 5 cm shorter than its base. This means that:
.
The area of the triangle is 25 cm²
By definition the area of a triangle is:
For this triangle we know that and . We substitute these values in the equation and solve for B.
Now we use the quadratic formula to solve the equation.
For an equation of the form the quadratic formula is:
In this case note that:
Then:
The solutions are:
For this problem we take the positive solution.
Now we substitute the value of B in the equation to find the height h
Answer:
1 is the slope
Step-by-step explanation:
When the equation of a line is written in the form
y = mx+b, m is the slope and b is the y intercept
y =x +9
y = 1x+9
1 is the slope and 9 is the y intercept
