4 / 1 (2x + 3) cube = 54 to find x value

4 / 1 (2x + 3) cube = 54 to find x value

4 / 1 (2x + 3) cube = 54
(2x+3)³=216=6³
2x+3=6
2x=3
x=3/2
X = 3 / 2

Cube of 2x = - 1 / 4

The cube of 2 is 8. Multiply both sides by a 1 / 8. The cube of X is - 1 / 32. The result is the cube root of - 2 / 4

In △ ABC, AC = BC, ad is the height of side BC, AE is the bisector of ∠ BAC, if ∠ ead = 18 °, then ∠ ACD =? I only know that there are two answers, I want to pass

Let angle B = angle cab = x, then angle bad = 90-x, angle bad + angle ead = 1 / 2 angle BAC, that is, 90-x + 18 = 0.5x, then the solution is x = 72 ° so ∠ ACD = 180-2x = 36 ° and another solution is that if ∠ ACD = x, then ∠ cab = ∠ ABC = 0.5 (180-x) ∠ CAD + ∠ DAE = 0.5 ∠ cab, that is, 90-x + 18 = 0.5 * 0.5 (180-x), then the solution is x = 84 °

() square meters equals 600 square decimeters,

(6) A square meter is equal to 600 square decimeters
If you don't understand, please ask, I wish you a happy study!

The average length of the top and bottom of a trapezoid is 30cm, and its height is 20cm. What is the area of the trapezoid in square centimeter?

30 times 2 is 60
60 times 20 and divide by 2

It is known that the similarity ratio of △ ABC to △ a1b1c1 is k = 2 / 3, then the perimeter ratio of △ ABC to △ a1b1c1 is a.3:2 b.2:3 c.4:9 d.9:4

B.2:3

If a = 2 / 3, then the value of a & sup2; - 2a-3 / A & sup2; - 7a + 12 is equal to________ .

(a²-2a-3)/(a²-7a+12)
=(a-3)(a+1)/((a-4)(a-3)
=(a+1)/(a-4)
=1+5/(a-4)
=1+5/(2/3-4)
=1-3/2
=-1/2

The star or the star, the moon or the moon is what song

Song title: the shadow of the fence Singer: Mao Amin, the star is still the star, the moon is still the moon, the mountain is still the mountain, and the beam is still the beam. The roller is the roller, the jar is the jar, the father is the father, the mother is the mother, the sesame oil lamp is still creaking, and the light is still on. Oh, oh, only the shadow of the fence is so

I forgot the chapter of the area formula of arbitrary triangle in which volume of senior high school

Compulsory five chapter one

Cube of [x + 2] + 1 / 8 = 0

(x + 2) ³ + 1 / 8 = 0
(x + 2) ³ = - 1 / 8
X + 2 = - 1 / 2
X = - 2-1 / 2
X = - 2 and 1 / 2
