Answer:

-3*-4=-12

Step-by-step explanation:

All other equations are correct. However, this equation is false, for when you multiply two negative signs, the answer is always positive:

-3 * -4 = 12

Please answer ASAP. The question is down below
Nadusha1986 [10]

Answer:  1) D      2) B

<u>Step-by-step explanation:</u>

1) The denominator cannot equal zero, Factor the denominator to find the zeros.  n³ - 4n² + 3n = 0

           n(n - 3)(n - 1) = 0

       n=0  n-3=0   n-1=0

       n=0    n=3      n=1

2) In order to be a rational expression, it must be in the form \dfrac{a}{b} where both a and b are integers.

Since \sqrtb\sqrt b is irrational and not an integer, then the expressions containing an irrational term <em>after simplified</em> cannot result in an integer.

Therefore, options <em>(i)</em> and <em>(iv)</em> are not rational expressions.

Option <em>(iii)</em> contains b as an exponent.  Since there is no information about b, it could be a fraction, which means it could be an irrational number.

The measurement of angles are :

  • Angle 1 is 123°
  • Angle 2 is 57°
  • Angle 4 is 123°
  • Angle 5 is 123°
  • Angle 6 is 57°
  • Angle 7 is 57°
  • Angle 8 is 123°

Given,

The figure with parallel lines.

Angle 3 is given as 57°

We have to find the other angles.

  • The measure of angle 1;

∠1 + ∠3 = 180° ; Sum of transversal angles is 180°

So,

∠1 = 180 - 57 = 123°

  • The measure of angle 2;

∠2 = ∠3 ; Vertical angles are ≅

So, ∠2 = 57°

  • The measure of angle 4;

∠1 = ∠4 ; Vertical angles are ≅

So, ∠4 = 123°

  • The measure of angle 5;

∠1 = ∠5 ; Corresponding angles are ≅

So, ∠5 = 123°

  • The measure of angle 6;

∠2 = ∠6 ; Corresponding angles are ≅

So, ∠6 = 57°

  • The measure of angle 7;

∠6 = ∠7 ; Vertical angles are ≅

So, ∠7 = 57°

  • The measure of angle 8;

∠5 = ∠8 ; Vertical angles are ≅

So, ∠8 = 123°

Step-by-step explanation:

Surface area of solid

= Area of Square + 4 * Area of Triangle

= (2)(2) + 4 * [(0.5)(2)(5)]

= 4 + 4 * 5

= 24 square inches. (3)
