<em>*Split the shape into 3 rectangles.</em>
<u>Rectangle 1:</u> 4 x 4 x 8 = 128
<u>Rectangle 2:</u> 14 x 4 x 4 = 224
<u>Rectangle 3:</u> 4 x 4 x 8 = 128
<u>Total:</u> 128 + 224 + 128 = 480 cm³
Answer: 22.55 mph
Step-by-step explanation:
Let the speed of the train be n
4 × 62 = 248 which is the distance travelled by the car in 4 hours and the train travelled in 11 hours
11 × n = 248
11n = 248
n = 248/11
n = 22.55mph
Answer:
10x-22
Step-by-step explanation:
((x+2)(x-1))-((x-4)(x-5))
(x^2-x-2)-(x^2-9x+20)
x^2 + x - 2
+ (-x^2+9x-20)
_______________
10x-22
