Identify ALL the terms that are like terms with 3x^2.

shutvik [7]

I think it would be 4x^2 and 3x^3 because they both have the same "x". Because you can't add, for example, 5x + 7z, they aren't alike. That's why you have to choose like terms, for example, 5x+ 5x= 10x.

I'm am very confused with this question.

stich3 [128]

Answer:

103°

Step-by-step explanation:

This is a cyclic quadrilateral (all vertices on the same circle)

Opposite angles are supplementary:

∠A + ∠C = 180°
∠B + ∠D = 180°

Find x:

x + 5 + x - 7 = 180°
2x - 2 = 180°
2x = 182°
x = 91°

Find D:

∠D = x - 14°
∠D = 91° - 14° = 77°

Find B:

∠B = 180° - 77° = 103°

- Mr. Sanders wants to display his American flag in a triangular case as shown below. 18.5 in What is the area of the triangular

Dmitriy789 [7]

Answer:

The area of the triangular case = 61.2 square inches

Step-by-step explanation:

P.S - The exact question is -

Given - Mr. Sanders wants to display his American flag in a triangular case as shown below.

To find - What is the area of the triangular case ?

Proof -

Given that,

Base of triangle = $14\frac{2}{5}in$

Height of triangle = 8.5 in

We know that,

Area of triangle = $\frac{1}{2}*Base*Height$

= $\frac{1}{2}*8.5*14\frac{2}{5}$

= $\frac{1}{2}*8.5*14.4$

= $\frac{1}{2}*122.4$

= 61.2

∴ we get

The area of the triangular case = 61.2 square inches
