add 4n and 5n, which is 9. 9n=-9, and if u divide both sides by nine, n=-1
Velocity is a measure of both speed and direction of motion. Velocity is a vector, which is a measurement that includes both size and direction. Velocity can be represented by an arrow, with the length of the arrow representing speed and the way the arrow points representing direction.
Answer:
62 square units
Step-by-step explanation:
The area of a rectangular prism is the sum of the areas of its six faces. Opposite faces have the same area, so it is the sum of 3 pairs of faces. The area of one face of each pair is the product of the dimensions of that face. Those three areas are ...
• L·W
• W·H
• H·L
so the total surface area is ...
A = 2(LW +WH +HL)
For hand calculation, this can be simplified a bit to ...
A = 2(LW +H(L+W)) . . . . . requires one less multiplication
For your prism, the area is ...
A = 2(5·2 + 3(5+2)) = 2(10 +21) = 62 . . . square units
Step-by-step explanation:
x- red candy
y- blue candy
x + y = 11
1.29x + .79y = 11.19
129x +79y = 1119
-129x -129y = -1419
-50y = -300
y = 6 lbs. blue
x + 6 = 11
x = 5 lbs. red
