Answer:
7
Step-by-step explanation:
Set up an equation where x is the number
2x = 14
Divide by 2 on each side
x = 7
So, the number is 7.
The residuals are the numbers shown next to each black line. Just total them:
15 + 10 + 11-10 +9 +10 +3-17-12 = 19.
The answer is B. 19
Y = 3x + b
Now plug in points
-7 = 3(-1) + b
-7 = -3 + b
b = -4
The y intercept is -4
1 + (-5) becomes 1 - 5 because you are adding a negative number.
1 - 5 is -4

Answer:
12.9 square yards
Step-by-step explanation:
The base is an equilateral triangle, so we can assume that the three faces have the same dimensions. Each of those face triangles has an area of ...
A = 1/2bh
A = 1/2(3 yd)(2 yd) = 3 yd²
The base area is computed using the same formula and the given height:
A = 1/2(3 yd)(2.6 yd) = 3.9 yd²
Then the total surface area is that of the base and the three faces:
SA = (3.9 yd²) + 3(3 yd²) = 12.9 yd² . . . total surface area
