<h3>I'll teach you how to distribute −2x(−10x+1)</h3>
----------------------------------------------------
−2x(−10x+1)
Apply the distributive law:
Ex. of distributive law:
a(b+c)= ab+ac
-2x(-10x)+(-2x)*1
Apply minus/plus rule:
2*10xx-2*1*x
Simplify 2*10xx-2*1*x:
2*10xx= 20x^2
2*1*x= 2x
20x^2-2x
Your Answer Is 20x^2-2x
plz mark me as brainliest if this helped :)
Answer:
see explanation
Step-by-step explanation:
(a)
The shaded figure is a trapezium with area (A)
A = 0.5 h(a + b)
where h is the perpendicular height and a, b the parallel sides, thus
A = 0.5 × 10 × (8 + 14) = 5 × 22 = 110 cm²
(b)
The volume (V) of the prism is calculated as
V = area of end face × depth
= 110 × 3 = 330 cm³
Answer:
426 cm^2
Step-by-step explanation:
Let, the area of the given figure be A
Let's imagine that the rectangle (at the bottom right) is present.
Then, A = Area of trapezium - Area of rectangle
= { 1/2 * ( 18 + (20+4) ) * ( 13+9 ) } - ( 4 * 9 )
= 462 - 36
= 426

Answer: The equation to solve is:
(x3y3+x2y2+xy+1)ydx+(x3y3−x2y2−xy+1)xdy=0
t3−t2−t+1t3+t2+t+1dt=dxx
any more help just ask :)
M 1 = V 1 * d
m 2 = V 2 * d
Both tetrahedrons have the same density.
V = 1/3 * a²√3/4 * h
V 1 = 1/3 * 1² * √3 / 4 * √2 / √3 = √2 / 12 cm³
V 2 = 1/3 * 3²√3 /4 * √6 = 9√2 / 4 cm³
m 1 : m 2 = √2 /12 : 9√2/4
m 1 * 9√2 / 4 = m 2 * √2 / 12
m 1 = m 2 / 27
m 1 + m 2 = 100 g
m 2 / 27 + m 2 = 100 g / * 27
m 2 + 27 m 2 = 2700
28 m 2 = 2700
m 2 = 2700 : 28
m 2 = 96.42 g
Answer:
The weight of the bigger tetrahedron is 96.42 g.
