-32
-12(-5) is 60
60+4 is 64
64/(-2) is -32 because two different signs is negative and the same sign is positive
Hope this helps

Idk Help meee please

Answer:

-9 =x

Step-by-step explanation:

We know these are similar triangles

We can use ratio's to solve

Let CS = y  and XR = y+y or 2y

y           x+19

------ = ------------

2y         x+29

We can simplify the ratio on the left by dividing by y

1           x+19

------ = ------------

2         x+29

Using cross products

1(x+29) = 2(x+19)

Distribute

x+29 = 2x+38

Subtract x from each side

x-x+29 = 2x-x+38

29 = x+38

Subtract 38 from each side

29-38= x+38-38

-9 =x

Well I got 17.5
You would start with                              6x1=6
Then you would add 7:                         6+7=13
Next you would multiply 13 by (1/2):    13(1/2)=6.5
Finally you would add 11 to 6.5:           6.5+11= 17.5

Solve for b 2 in A = h(b 1+b 2), if A = 16, h = 4, and b 1 = 3. b 2 =
hammer [34]

Answer:

b2 = 1

Step-by-step explanation:

A = h(b1 + b2)

Given:

A = 16

h = 4

b1 = 3

b2 = x

Work:

A = h(b1 + b2)

16 = 4(3 + x)

16 = 12 + 4x

4x = 16 - 12

4x = 4

x = 1
