Y=x^2+2;D:-1, 0, 1, 2, 3

Mathematics
1 answer:
IrinaK [193]3 years ago
8 0

For the various values of X the values of Y are given as follows

X=-1; Y=3

X=0; Y=2

X=1; Y=3

X=2; Y=6

X=3; Y=11

Step-by-step explanation:

Step 1:

Let us consider the given expression as

Y= X^{2} + 2

Step 2:

Let us discuss the value of Y for the various values of X

If X = -1, Y = (-1)² + 2 = 3

If X = 0, Y = (0)² + 2 = 2

If X = 1, Y = (1)² + 2 = 3

If X = 2, Y = (2)² + 2 = 6

If X = 3, Y = (3)² + 2 = 11

There are two consecutive even numbers such
Bond [772]

Step-by-step explanation:

Let the numbers be x and y

2 consecutive even nos.

therefore y = x+2

twice of the first (2x) is 46 more than y

2x = y+46

Solving both the equations

x - y + 2 = 0

(-)2x - y - 46 = 0

____________

-x + 0 + 48 = 0

____________

x = 48

y = x+2

= 48 +2

= 50

Therefore the 2 nos. are 48 and 50

Hope this answers helps you

Is LMN a right triangle?
adoni [48]

Answer:

True

Step-by-step explanation:

We can sue the pythagorean theorem to verify. 15^2+36^2 should equal the longest side squared or 39^2. If we plug in the numbers, it checks out!

The perimeter of a square is 52 cm.<br> Calculate the area of the square
Nonamiya [84]

Answer:

169cm^2

Step-by-step explanation:

The perimeter is the sum of the side lengths of the shape. Since a square has equal side lengths, each side must be the same. Divide 52/4=13cm. 13cm is the length of 1 side. Area is length times width, and since each side is 13, multiply 13cm*13cm to get the area, which is 169cm^2,

3x^2 (x^2 - 4x - 2) + (5x^3 + 7x^2+2x+11) plz show work
matrenka [14]

Let's simplify step-by-step.

3x2(x2−4x−4)+5x3+7x2+2x+11

Distribute:

=(3x2)(x2)+(3x2)(−4x)+(3x2)(−4)+5x3+7x2+2x+11

=3x4+−12x3+−12x2+5x3+7x2+2x+11

Combine Like Terms:

=3x4+−12x3+−12x2+5x3+7x2+2x+11

=(3x4)+(−12x3+5x3)+(−12x2+7x2)+(2x)+(11)

=3x4+−7x3+−5x2+2x+11

Answer:

=3x4−7x3−5x2+2x+11
