The perimeter of a triangle is side a + side b + side c. so...
(2x + 4) + (2x + 4) + (2x + 4) = 6x + 12.
But if you need to go farther...
6x = -12
x = -2
then replace x in the original equation with -2......
2(-2) + 2(-2) + 2(-2)
multiply
(-4) + (-4) + (-4)
add
the answer should be -12
X=(3/7)+y/7
this is the correct answer for x\
Answer:
the answer is c
Step-by-step explanation:
The biggest one is 999.
If you started counting from 1 to 999, you would count to 99

Answer:
75.5 % of all candidates passes
Step-by-step explanation:
36000 x .45 = 16200 x .7 = 11,340 girls passed
36000 x .55 = 19800 x .8 = 15,840 boys passed
total of boy and girls who passed = 27,180
27,180 out of 36,000 equals 75.5%
