Evaluate 10 8 ÷ 2 − 4. (5 points) 10 5 6 14

The answer is 23, it's easy, you shouldn't need help on this and you gotta learn that because one day, you're gonna copy an answer you know you got right but you get it wrong because it wasn't your answer.

Step-by-step explanation:

Follow the PEMDAS order of operations

Multiply and divide (left to right) 16 / 2:    8

= 20 + 8 - 5

Add and subtract (left to right) 20 + 8 - 5:    23

= 23

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

she gotta workk that a 2
