Answer:
never learned it sssssooooooorrrrrrrryyyyyyy!!
Step-by-step explanation:
You can factor -80 as
So, we have
The square root of a product is the product of the square roots:
Since and , we have
Work out 6% of $42 which equals to $2.52. The work out what 20% of $42 which is $8.40. Finally add the $8.40 and $2.52 onto $42 to give you your answer of $52.92
If you divide 416 to 13, the answer is 32. Hence, each friend will get 32 crayons.
EC bisects so m<BEC = m<CED
11x - 12 + 2(4x + 1) = 180
11x - 12 + 8x + 2 = 180
19x - 10 = 180
19x = 190
x = 10
m<AEB= 11x - 12 = 11(10) - 12 = 98
m<CED = 4x+1 = 4(10) + 1 = 41
m<BEC = m<CED = 41
so
m<AEC = m<AEB + m<BEC
m<AEC = 98 + 41
m<AEC =139
answer
m<AEC =139
