Factorization (2a + b) (2a-b) + a (2a + b)

Factorization (2a + b) (2a-b) + a (2a + b)

(2a+b)(2a-b)+a(2a+b)
=(2a+b)(2a-b+a)
=(2a+b)(3a-b)

When a 40cm long cylinder is cut off a 10cm long section, the surface area is reduced by 1256cm2. What is the surface area of the original cylinder?

Bottom perimeter = reduced surface area △ reduced height = 1256 △ 10 = 125.6cm bottom radius = bottom perimeter △ 2 * 3.14 = 125.6 △ 6.28 = 20cm 2 bottom areas = 2 * 3.14 * 20 * 20 = 2512cm2 original side area = bottom perimeter * height = 125.6 * 40 = 5024cm2 surface area = side area + bottom area =

What is the greatest common factor and the least common multiple of 50 and 75

Mamma Mia! Primary school problem. The greatest common factor is 25. The least common multiple is 150

Triangle ABC AB = AC, the lengths of both sides are 5 and 6, find the circumference of triangle ABC

The length of side is 5 and 6, because AB = AC, so AC = AB = 5 or 6

The greatest common divisor of a and B is 12, the least common multiple is 180, a is 60, and B?

180÷60×12=36

For example: A1 B1 C1 D1 E1 F1 G1 H1 I1 J1 K1 L1 M1 I only want the value of A1 C1 E1 G1 I1 K1 M1

=SUMPRODUCT((MOD(COLUMN(A1:M1),2)=1)*A1:M1)/7

What is the plural of strawberry?

If the coordinate of the intersection of the parabola y = ax ^ 2-2ax + C (a ≠ 0) and the X axis is (- 1,0), then the coordinate of the other intersection of the parabola and the X axis is -______ .

Y = ax ^ 2-2ax + C (a ≠ 0) and x-axis,
Axis of symmetry x = - (- 2A) / a = 2
x=(x1+x2)/2
x2=2x-x1=2*2-(-1)=5
The coordinate of the other intersection point with the X axis is (5,0)

Given a = 2x ^ 2-5xy + 2Y ^ 2 + x-2y, B = x ^ 2-5 / 2XY + y ^ 2-2x + y, and a-2b = 3A, the absolute value of x-a + (Y-1) ^ 2 = 0, find the value of A

First of all, from x-a + (Y-1) ^ 2 = 0, x-a ≥ 0, (Y-1) ^ 2 ≥ 0, we can know that x-a = 0, (Y-1) ^ 2 = 0, that is, x = a, y = 1, a = 2x ^ 2-5xy + 2Y ^ 2 + x-2y, B = x ^ 2-5 / 2XY + y ^ 2-2x + y is substituted into a-2b = 3A, after simplification, 5x-4y = 3A, x = 2, y = 1 is substituted into the above formula, a = 0 is obtained
