Answer:

-4x^2 + 3x +1 & it would be C. quadratic trinomial

Step-by-step explanation:

1: <u>Remove the parenthesis. Switch the -1 to a +1</u>.

8x^2 + 3x - 12x^2+1

2: <u>Simply the equation</u>.

8x^2 + 3x - 12x^2+1

 (2a. Group like terms)

= 8x^2 -12x^2+3x+1

 (2b. Add the similar elements)

= -4x^2 + 3x + 1

So you would minus 12x^2 and 8x^2 to get 4x^2!

If the side length of a square is 4 inches, it’s area is how many square inches and it’s perimeter is how many inches
riadik2000 [5.3K]

Answer:

The area is 16 inches squared and the perimeter is also 16 inches

Step-by-step explanation:

To find the area, you must multiply the length by the width. Since this is a square, you have to multiply one adjacent side by the other. For perimeter, you can either multiply one side by 4 or add all 4 sides.

State whether the triangles are similar. If so, write a similarity statement and the postulate or theorem you used. The diagram
olga55 [171]

Givn : OK = 3, OJ = 30, KN = 1, JM = 3

ON=OK+KN=3+1=4

OM=OJ+JM=30+10=40

In triangles OKJ & ONM,

OKOJ=330=110

ONOM=440=110

Angle O is common in both the triangles.

Two sides are in same proportion and the included angle is common (SAS) . Hence both the triangles are similar.

That means KJNM=110 or the two sides are parallel.

Hence ˆK=ˆN,ˆJ=ˆM corresponding angles.
