X=4
If you plug in 4 for x you should get 49 which would add up with the other angles to equal 180

HELP PLS MANY POINTS Use the function f(x) to answer the questions: f(x) = 4x2 + 8x − 5 Part A: What are the x-intercepts of the
Andrei [34K]

Answer:

see below

Step-by-step explanation:

f(x) = 4x^2 + 8x − 5

To find the x intercepts set y = 0

0 =4x^2 + 8x − 5

Factor

0=(2x-1)(2x+5)

Using the zero product property

2x-1 =0     2x+5 =0

2x=1            2x = -5

x = 1/2           x = -5/2

The x intercepts are ( 1/2 ,0)   and ( -5/2,0)

Rewriting in vertex form by completing the square

4 ( x^2 + 2x) -5

4 ( x^2+2x +1) -4*1 -5

4 ( x+1) ^2 -9

Vertex form is

a( x-h) ^2 +k  where ( h,k) is the vertex

The vertex is ( -1,-9)

We know it opens upwards since a > 0

Plot the vertex and the x intercepts

The graph is symmetric on  based on the vertex

The length of a rectangle is one unit more than the width. if the area is 30 square units find the dimensions of the rectanhgle
solmaris [256]
Width = w

Length = w + 1

Area = 30

w(w+1) = 30

w² + w = 30

w² + w - 30 = 0

w² + 6w - 5w - 30 = 0

w(w + 6) -5(w + 6) = 0 

(w + 6)(w - 5) = 0

w = 5 or -6

Since the width cannot be negative, the width is 5 units.

Hence, the width is 5 units and the length is 6 units.

Eiko is wearing a magic ring that increases the power of her healing spell by 30%. Without the ring, her
Butoxors [25]

Answer:

The correct answers are B and C.

Step-by-step explanation:

3/10 + 1 represents an extra 30%, plus 100%. The 100% accounts for the original power of the spell. The expression can be simplified as 1.3H, or 130% of H. 130% of H can also be represented as 130/100 H.
