A photograph of a painting measures 13 units by 17 units. If the scale factor is 1/3, what is the actual size of the painting?

Answer:

39 units by 51 units

The painting is a scale factor of 1/3, so each side length is 1/3 of the original.  To find the original multiply both side lengths by 3.

13x3 = 39

17 x 3 = 51

Help help help if u can answer this I’ll mark u brainliest (6) (the one in the middle)
Hoochie [10]

You just have to plug in each thing:

So f(0):

3(0)^2 - 4 = -4

so its not A

f(-2) and f(2):

3(-2)^2 - 4

3(2)^2 -4

now we don't even have to calculate these, anything to the power of an even number is a positive number so -2^2 and 2^2 both equal 4

B is correct, so you can do the others if you want to check, but if B is true the others shouldn't be true.

Find the value of x
zloy xaker [14]

Answer:

66

Step-by-step explanation:

EHG is a straight line so it is 180°.

You already know the value of FHG, so you can find the value of 2x.

180° = 48° + 2x

2x = 180° - 48°

    = 132

x = 132° ÷ 2

  = 66
