Which algebraic expression is a polynomial with a degree of 2? 4x3 − 2x 10x2 − StartRoot x EndRoot 8x3+ StartFraction 5 Over x E
kati45 [8]

Answer:

6x^2 - 6x + 5

Step-by-step explanation:

Given

List of Options

Required

Which of the options has a degree of 2

The general format of a polynomial is

ax^n + bx^{n-1} + ..... + cx^{n-n}

<em>Where n represents the degree </em>

In this case;

n = 2

Substitute 2 for n in expression above;

ax^n + bx^{n-1} + ..... + cx^{n-n}

ax^2 + bx^{2-1} + ..... + cx^{2-2}

ax^2 + bx^{1} + ..... + cx^{0}

ax^2 + bx + c *1

ax^2 + bx + c

Comparing this format to the list of given options; the option with the same format is: 6x^2 - 6x + 5

Where a = 6; b = -6 and c = 5

<em>Hence, the polynomial with a degree of 2 is </em>6x^2 - 6x + 5

Can someone help me these 2 questions? PLS and ty!
adelina 88 [10]

Answer:

y=60° b=60°

Step-by-step explanation:

the sum of all degrees of interior triangle is 180

in the first one, 30° and 90° have been given.(that small square represent 90°)

so 180°-90°-30°=60°

in the second one, the 120° is on the other side of a line, a line has a degree of 180, therefore the interior angle is 60°, the same rule 180°-2*60°=60°
