Answer:
area = 2236 in²
Step-by-step explanation:
area of a triangle = 1/2 b h
b = 86
h = 52
plug in values
area = 1/2 * 86 * 52
area = 2236 in²
4.2 is the answer. Hope this answered your question
Answer:
a = 5/6 , b = -3/10
Step-by-step explanation:
3a-5b:3a+5b=1:4
3a-5b / 3a +5b = 1/4
Cross multiply
3a -5b =4 ..........(1) solve simultaneously
3a + 5b = 1 ..........(2) using elimination method
-----------------------
Add equation 1 and 2
6a = 5
Divide both sides by 6
6a/6 = 5/6
a =5/6
Put value of a into equation 2
3a +5b = 1
3(5/6) + 5b = 1
5/2 + 5b = 1
5b = 1 - 5/2
5b = - 1½
5b = - 3/2
Divide both sides by 5
5b/ 5 = -3/2 ÷ 5
b = -3/2 × ¹/5
b = - 3/10
Therefore a = 5/6 , b = -3/10

The answer is 168 because 11 x 6 is 66 but on a triangle it would be half of that cause the formula of a triangle a = bh/2 so thats 33 and since theres 4 sides you would do 33 x 4 = 132 then 6 x 6 cause the base of the triangle = 36 and 132 plus 36 is 168
Answer:
B
Step-by-step explanation:
Distributive property is when you use the number on the outside of the parenthesis to multiply to the inside. So, 36+9=3(12+3), in order to solve it on the parenthesis side you would take 3 and multiply it by 12, giving you 36. Then, you would take 3 and multiply it to the other 3 which gives you 9.
