Can anyone help please
Akimi4 [234]

Answer: X = 27

Step-by-step explanation: If we observe very closely, we have two similar triangles in the diagram. The first one is ABC and the other triangle is EDC. Also take note that angle ACB in the first triangle is equal in measurement to angle ECD (45 degrees) in the other triangle, (Opposite angles).

Hence in triangle ECD, we have identified two angles so far which are angle 2x + 10 and angle 45. Same applies to triangle ABC, we already have two angles which are, 3x - 10 and 45.

However angle D in the second triangle is equal in measurement to angle B in the first triangle

(Alternate angles).

Hence we have a third angle in triangle ABC which is

Angle B = 2x + 10.

Therefore 3x - 10 + (2x + 10) + 45 = 180

(Sum of angles in a triangle)

3x - 10 + 2x + 10 + 45 = 180

By collecting like terms we now have

3x + 2x = 180 + 10 - 10 - 45

5x = 135

Divide both sides by 5,

x = 27

Which point is an x-intercept of the quadratic function f(x) = (x + 6) X – 3)?
Anni [7]

Answer:

(-6, 0) and (3, 0)

Step-by-step explanation:

I think you meant f(x) = (x + 6)(x - 3).  This graph intersects the x-axis in two places:  (-6, 0) and (3, 0).  These are the "x-intercepts."

Answer:

C. $8483

Step-by-step explanation:

To find the  coffee sales, we plug in the value of x as 34 into y = 60x + 6443.

  • y=60(34)+6443
  • y=2040+6443
  • y=8483

Therefore, the answer is C. $8483.00.

A 14 14​-foot board is cut into two pieces. If one piece is x feet​ long, express the other length in terms of x.
xxTIMURxx [149]

Answer:

x = first piece

14 - x = second piece

Step-by-step explanation:

Since we know that the board is 14 feet then to find the size of the second piece, we just take the full length of the board and then subtract it to the first piece's length.
