27) 3 (-5) (-7)
When there is no math symbol between numbers it is multiplication.
Multiply from left to right:
3 * -5 = -15
-15 * -7 = 105
28) -2 * 2 (-3) *2 =
-2 *2 = -4
-4 * -3 = 12
12*2 = 24
31) A negative divided by a negative is positive:
-128 / -4 = 32
32 -36 / 2 / 24 /4
Divide the top and bottom first then divide those:
-36 / 2 = -18
24 / 4 = 6
-18 / 6 = -3
Answer:
Vertical line of symmetry, from midpoint of top to midpoint of bottom
Horizontal line of symmetry, from midpoint on left to midpoint on right.
Rotational line of symmetry on the two diagonals.
Step-by-step explanation:
Answer:
cosA = - 
Step-by-step explanation:
Using the double angle identity
cos2A = 2cos²A - 1 , then
cosA = 2cos²(
) - 1 , that is
cosA = 2 × (
)² - 1
= 2 × 
- 1
= 
- 
= -
