9.5
and
9
a square has 4 sides and i’m ~assuming~ they’re equilateral, so take the area and divide it by 4.
im not 100% sure but maybe this will help a little bit!! :)
Answer:
Data set A best fit by the regression line.
6. 13
7. 262
8. ? For the first part but the sum is $118
9. ?
Use the least common denominator(LCD) to solve this equation:
1 + (-2/3) - (9/2)
so, what is the LCM of 3 and 2 : 6
so, the LCD = 6
1 + (-2 x 2/6) - (9 x 3/6)
the 1 = 6/6
Put it back into the equation:
6/6 + (-4/6) - (27/6)
Then, take it out of the parenthesis:
6/6 - 4/6 - 27/6
Simplify:
= - 25/6
which is the answer.
Hope that helped !! Have a great day now
Answer:
x = 9
Step-by-step explanation:
AB = 4x + 6 and BC = 7x + 15 AC is the sum of AB and BC
so 4x + 6 + 7x + 15 = 120 add like terms
11x + 21 = 120 subtract 21 from both sides
11x = 99 divide both sides by 11
x = 9
