Multiple Choice

Answer:

B. P = 70 in; A = 300 in²

Step-by-step explanation:

The perimeter is the sum of the side lengths. Opposite sides are the same length, so the perimeter is ...

P = 20 in + 15 in + 20 in + 15 in = 2(20 in +15 in) = 2(35 in)

P = 70 in.

Only answer choice B has the correct value. (Its area figure is also correct.)

A climbing structure needs to be built in the shape of a square-based pyramid. Look at the diagram below. What is the perimeter

Marta_Voda [28]

Answer:

40 m

Step-by-step explanation:

The perimeter of the flat, orange shape is the sum of all the sides that forms a boundary around the shape.

The shape is made up of 4 triangles having 2 equal side lengths each, which surrounds the center square.

Each side length of the triangle, that forms a boundary round the shape = 5 m.

There are 8 of this equal side length.

Perimeter = 8(5m) = 40 m

Which of the following constants can be added to x2 - 3x to form a perfect square trinomail?

serious [3.7K]

The constant that can be added to $x^2$ - 3x to form a perfect square trinomial is $2\frac{1}{4}$

The given expression is

$x^2$ - 3x

To form a perfect square trinomial

$(a-b)^2 =a^2-2ab+b^2$

The given expression is

$x^2$ - 3x

first we have to add a constant term with it

$x^2$ - 3x + z

By comparing the given expression and the perfect square trinomial

$a^2 =x^2$

a = x

Similarly

-2ab = 3x

where know a =x

Then,

-2b = 3

b = -3/2

Similarly

$b^2 = z$

$(\frac{-3}{2})^2$ = z

9/4 = z

Convert the simple fraction to mixed fraction

9/4 = $2\frac{1}{4}$

Hence, the constant that can be added to $x^2$ - 3x to form a perfect square trinomial is $2\frac{1}{4}$

The complete question is :

Which of the following constants can be added to x2 - 3x to form a perfect square trinomial?

$1\frac{1}{2},2\frac{1}{4}$ and $4\frac{1}{2}$
