Answer:
Therefore she needs 1095 mm²to paint the top and sides.
Step-by-step explanation:
Given that Kissing needs to paint the top and side of rectangular prism has a length = 25 mm ,width= 15 mm and height = 9 mm.
The rectangular prism has 6 face.
The floor of the prism is not painted.
Only sides and top is painted.
The surface area of the sides and top is
= 2(length + breadth)×height+ (length × breadth)
=[2(25+15)×9 +(25×15)] mm²
=1095 mm²
Therefore she needs 1095 mm²to paint the top and sides.

Answer:
i) x points; ii) 2x - 75 = -25; iii) x = 25
Step-by-step explanation:
i) Starting points
Let's say you had x points before doubling your score.
(ii) The equation
After doubling score: 2x points
After losing 75 points: (2x - 75) points
At end of game: -25 points
The equation is
2x - 75 = -25
iii) Solution to equation
2x - 75 = -25 Add 75 to each side
2x = 50 Divide each side by 2
x = 25
Answer:
The answer to your question is: letter A
Step-by-step explanation:
From the graph we get the points,
P (2,1)
Q (6,8)
Formula
d = √((x2-x1)² + (y2-y1)²)
d = √((6-2)² + (8-1)²)
d = √ (4² + 7²)
d = √ (16 + 49
d = √65 letter A
