Evaluate the expression 2(8 − 4)2 − 10 ÷ 2.

1 answer:

6 0

2(8-4)2-10/2, 8 - 4 is 4 so then times that by 2 and you'll get 8 then multiply that by 2 to get 16, after that you need to subtract it by ten which is 6 then divide it by 2 to get 3.

Hope this helped

Geometry please help!

Answer:

see explanation

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

The polygon here has 8 sides, that is n = 8, thus

sum = 180° × 6 = 1080°

Sum the given angles and equate to 1080, that is

14x + 133 + 167 + 138 + 18x + 115 + 151 + 120 = 1080

32x + 824 = 1080 ( subtract 824 from both sides )

32x = 256 ( divide both sides by 32 )

x = 8

Thus the 2 unknown angles are

14x = 14 × 8 = 112°

18x = 18 × 8 = 144°

Y = - 2x + 2 2x + y = 2 What is the solution to this ?? Pls helpppp

Anna35 [415]

Answer:

Infintely many solutions

Step-by-step explanation:

I'm going to assume that the capital y is equal to the lowerase y

if you subtract y and two from both sides in the second equation you get

-y=2x-2

you then divide by -1 to get it into a normal form

y= -2x+2

this is the same as the first equation, these lines are the same
