Mathematics
1 answer:
____ [38]3 years ago
4 0

<span> Given polynomial x^2+8x-48 = 0</span>

<span>x^2+12x-4x-48 = 0</span>

<span>x(x+12)-4(x+12) = 0</span>

<span>(x+12)(x-4) = 0</span>

<span>x+12 = 0</span>

Subtract 12 from each side.

<span>x+12-12 = 0-12</span>

<span>x = -12</span>

<span>and x-4 = 0</span>

Add 4 to each side.

<span>x-4+4 = 0+4</span>

<span>x = 4</span>

<span>Roots are -12,4.</span>

A triangle has side lengths of ( 4h + 2k) centimeters, (9h + 4m) centimeters, and (2m - k) centimeters. Which expression represe
enot [183]

Answer:

P = (13h+k+6m) cm

Step-by-step explanation:

Given that,

The side lengths of a triangle are :

(4h + 2k) cm, (9h + 4m) cm, and (2m - k) cm

We need to find the perimeter of the triangle.

We know that,

Perimeter = sum of all sides

So,

P = (4h + 2k)+(9h + 4m)+(2m - k)

= (4h+9h)+(2k-k)+(4m+2m)

= 13h+k+6m

Hence, the perimeter of the triangle is (13h+k+6m) cm.

Determine the measures of the angles marked with letters​
Arturiano [62]

1) Now,

a + 27° = 90° (right angle triangle)

◆ a = 63°

2) Now,

b + b + b = 90° (right angle triangle)

or, 3b = 90°

◆ b = 30°

3) Now,

c + c + 40° = 90° (right angle triangle)

or, 2c = 90° - 40°

or, c = 50°/2

◆ c = 25°

4) Here,

◆ e = 41° (vertically opposite angle)

◆ f = 82° ( vertically opposite angle)

Now,

d + e + f = 180° (straight angle)

or, d + 41° + 82° = 180°

or, d = 180° - 123°

◆ d = 57°

Then,

◆ g = d = 57° (vertically opposite angle)

It is all correct answer...

I hope u understand...

Thank you ♥♥ my cutie...

Which of the following functions is graphed below?
Ghella [55]
Selection A is appropriate.

_____
The black dot on the graph means that one of the regions of interest will be
  x ≤ 1

The y-intercept for the left branch of the graph is -4, so we khow that
  y = x³ -4, x ≤ 1
will be part of the function definition.
