Step-by-step explanation:
The area = 3 × 10 = 30
The perimeter = 2(3 + 10) = 26
please give me a brainliest answer
The perimeter of a triangle is when u add all of the sides together
(8x - 7w) + (2x + 6y) + (3y + 5w) =
10x + 9y - 2w is ur perimeter
8w + 12x - 9y
8w + 12x - 9y
8w + 12x + 5y
8w + 12x - 9y
the 1st, 2nd, and 4th answer choices are the same....so 3 of them are equal
-4
Step-by-step explanation:
2(-3)-3y=6
-6-3y=6
-3y=12
y=-4

Answer:
1 r= 68/55
2 no solution
Step-by-step explanation:
Answer:
∠2 = 51°
Step-by-step explanation:
The sum of supplementary angles = 180°
Equate the sum of the angles to 180 and solve for a
11a + 19 + 6a - 9 = 180
17a + 10 = 180 ( subtract 10 from both sides )
17a = 170 ( divide both sides by 17 )
a = 10
Hence
∠2 = (6 × 10) - 9 = 60 - 9 = 51°
