An outside angle equals the sum of the two opposite inside angles.

So you have:

(5x-35) = 2x +58

Solve for X then you can calculate Angle B:

(5x-35) = 2x +58

Subtract 2x from both sides:

3x -35 = 58

Add 35 to both sides:

3x = 93

Divide both sides by 3:

X = 93 /3

x = 31

Now for Angle B, replace x with 31:

Angle B = 2x = 2(31) = 62 degrees.

Identify the zeros of the polynomial function N(x)=1/2 (x-1)(x+3).
zhannawk [14.2K]

Answer:

a:x=-3

c:x=1

Step-by-step explanation:

The zeros of a function are the values of x for which the value of the function f(x) becomes zero.

In this problem, we have the following function:

f(x)=\frac{1}{2}(x-1)(x+3)

Here we want to find the zeros of the function, i.e. the values of x for which

f(x)=0

In order to make f(x) equal to zero, either one of the factors (x-1) or (x+3) must be equal to zero.

Therefore, the two zeros can be found by requiring that:

1)

x-1=0\\\rightarrow x=+1

2)

x+3=0\\\rightarrow x=-3

So the correct options are

a:x=-3

c:x=1

Which number is bigger: 0.135 or 0.14?
Fofino [41]
0.14 as if you convert it into like decimal (add a 0 if the places are not the same e.g. 0.1 and 0.02 here 0.1 does not have the same number of digits so add a zero so it becomes 0.10 :. 0.10 is bigger then 0.02) (note the value of 0.1 will remain the same) so here 0.14 will become 0.140 :. bigger than 0.135
