Answer:

X=140

Step-by-step explanation:

<em>Firstly, any Quadrilateral has a total sum of its angle equal to 360 degrees</em>

<em>The attachment you are showing us shows that we already know two angles</em>

<em>(70)&(60) degrees. I am assuming the line DC is a tangent, so angle ADC must be 90 degrees since a full angle on a tangent is equal to 180 degrees and there is 90 from the other side (180-90=90). Now we know 3 angles and what you have to do is find X so that when you add them all up they make a sum of 360. </em>

<em />

X+70+60+90=360

X=360-70-60-90

X=140

Given f(x) = x² + 2 and g(x) = x + 14<br>Find the values of a such that f(a) = g(a)​
Minchanka [31]

Answer:

a = - 3, a = 4

Step-by-step explanation:

Given f(x) = x² + 2 and g(x) = x + 14 , then

f(a) = a² + 2 and g(a) = a + 14

For f(a) = g(a) , then equate the right sides

a² + 2 = a + 14 ( subtract a + 14 from both sides )

a² - a - 12 = 0 ← in standard form

(a - 4)(a + 3) = 0 ← in factored form

Equate each factor to zero and solve for a

a + 3 = 0 ⇒ a = - 3

a - 4 = 0 ⇒ a = 4

What is the degree classification of this polynomial?<br> x^2+4x-8
Darina [25.2K]

You can find the degree classification by what is the greatest power shown in the polynomial. In this case, your answer is 2. Remember, it will be easier to find the degree when you order the terms from greatest to least by powers.
