A Pennant is shaped like a isosceles triangle the short side is 14 inches long and is half the length of each longer side find a perimeter of a pennant

70

Step-by-step explanation:Since its isosceles, two of the numbers are the same. 14 is half the length of the each long side, making one side 28, and the last side also 28 since its isosclees. When you add all these sides together (28+28+14) you get 70. So that would be your answer

the perimeter of the pennant is 70 inches.

Step-by-step explanation:

The formula for determining the perimeter of a triangle is expressed as

Perimeter = a + b + c

Where a, b and c are the length of each side of the triangle.

In an isosceles triangle, two sides are equal. Therefore, if the short side is 14 inches long and is half the length of each longer side, it means that the length of each longer side is 14 × 2 = 28 inches

Therefore, the perimeter of the pennant would be

Perimeter = 14 + 28 + 28 = 70 inches

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
