The width of a rectangular garden is 32 meters. Now the width of the garden is increased by 6 meters, and the area is increased by 360 square meters. What is the area of the garden now?

The width of a rectangular garden is 32 meters. Now the width of the garden is increased by 6 meters, and the area is increased by 360 square meters. What is the area of the garden now?

Divide the increased area by the increased width of the garden to calculate the length of the garden, and use the original width. Add the increased width to calculate the width that appears in the garden. Multiply the current width by the length and meter to calculate the area that appears in the garden!

There is a rectangular lawn in the park, 62 meters long. We need to increase the width by 35 meters and keep the length unchanged. What is the area of the expanded lawn?

35*62＝280

Factorization of a + ax + ax ^ 2 + x ^ 2-1

(a+1)*x^2+a*x+a-1
If the original title is changed to: a + A * x + A * x ^ 2 + x ^ 3-1
It can be decomposed into: (1 + X + x ^ 2) * (x + A-1)

Eight minus (three and two thirds plus two and four fifths)

8 - (3 and 2 / 3 + 2 and 4 / 5)
=8 - [(3 + 2) + (2 / 3 + 4 / 5)]
=8 - [5 + (10 / 15 + 12 / 15)]
=8 - (5 + 1 and 4 / 5)
=8-6 and 4 / 5
=One and one in five

50 square logs are piled into a cuboid with a length of 2m, a width of 1m and a height of 1.5m. What is the average volume of each one?

2 * 1 * 1.5 = 3m3
3 / 50 = 0.06 M3
The volume of each square wood is 0.06 cubic meters

8 out of 20 is 20 to what

8/20=0.4:1=20:50

Divide 100 into the sum of two natural numbers, one is the multiple of 11, the other is the multiple of 17, these two numbers are

66
thirty-four

18 * 970-330 * 15 (simple operation)

18*970-330*15
=18*(1000-30)-(300+30)*15
=18*1000-18*30-300*15-30*15
=18000-4500-(18+15)*30
=13500-23*30
=13500-690
=13810

1. When 2 = 2, B = 3, a = - 2, B = - 3 and a = - 2, B = - 3, the values of a & # 178; - 2Ab + B & # 178; and (a-b) &# 178; are calculated respectively
2. According to the above calculation results, what is the relationship between the size of a & # 178; - 2Ab + B & # 178
3. Using the law you found, find the value of 12.57 & # 178; - 2 × 12.57 + 2.57 & # 178
It's urgent

A-b-178; - 2Ab + b-178; = 1 and (a-b) - 178; = 1
According to the above calculation conjecture a & # 178; - 2Ab + B & # 178; = (a-b) &# 178;
12.57²－2×12.57＋2.57²=(12.57-2.57)^2=10^2=100
