Answer:
16 units.
Step-by-step explanation:
Just to make things easy, let's name the points A(3,9) B(5,9) C(3, 3) and D(5, 3).
Because this question wants perimeter, we'll just use the distance formula twice, then l*2 + w*2 = p.
Distance formula is sqrt((x1 - x2)^2 + (y1 - y2)^2) = d.
sqrt((5 - 3)^2 + (9 - 9)^2) = 2
sqrt((5 - 5)^2 + (9 - 3)^2) = 6.
The distance of points A and B is 2 units, and B to D is 6 units, multiply both by 2, (2*2=4, 6*2=12) and add the values to find 16 units.
Hope this helps, and if this is for OW, I feel your pain.
Answer:
a = 9
Step-by-step explanation:
Simplifying
8.1 = 0.9a
Solving
8.1 = 0.9a
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-0.9a' to each side of the equation.
8.1 + -0.9a = 0.9a + -0.9a
Combine like terms: 0.9a + -0.9a = 0.0
8.1 + -0.9a = 0.0
Add '-8.1' to each side of the equation.
8.1 + -8.1 + -0.9a = 0.0 + -8.1
Combine like terms: 8.1 + -8.1 = 0.0
0.0 + -0.9a = 0.0 + -8.1
-0.9a = 0.0 + -8.1
Combine like terms: 0.0 + -8.1 = -8.1
-0.9a = -8.1
Divide each side by '-0.9'.
a = 9
Simplifying
a = 9
Answer:
same i cant see any of the answers but sometimes the answers are in the questions. so just read the question over again and maybe it will be there.
