<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:
No
Step-by-step explanation:
You should only use t procedures when the sample sizes are less than 30, as that is when the Central Limit Theorem kicks in.
Essentially, t procedures are good for small samples while z procedures are better for larger samples.

65°
Step-by-step explanation:
m∠KJL = 65°
Answer:
915 in²
Step-by-step explanation:
The area of the rectangle :
Length = 32 inches
Width = 25 - (10+10) = 25 - 20 = 5 inches
Area of rectangle = Length * width
Area = 32 * 5 = 160 in²
Area of triangle :
Base = 25 inches
Height = (46 - 32) inches = 14 inches
Area of triangle = 1/2 * base * height
Area of triangle = 1/2 * 25 * 14 = 175 in²
Total area = (160 + 175)in² = 335 in²
Total area of cardboard :
50 inches * 25 inches = 1250 in²
Amount of cardboard not used :
(1250 - 335) in² = 915 in²
Answer:
D
Step-by-step explanation:
For the first 3 digits the possibilities are
10*9*8 since there is no repeating
The last two letters possiblities are
26*25
10*9*8*26*25 = 468,000
