She made her first mistake in step 2
-2x+5 =-11
add 5 to each side
-2x-5+5 = -11+5
-2x = -6 (not -16)
divide by -2
-2x/-2 = -6/-2
x = 3
She added 5 to 11 and got 16 and made it negative instead of subtracting 5 from 11 and making it negative
Answer:
natural numbers
Step-by-step explanation:
i say this cause this is a negative integers number 0 and positive integers which make it natural number
Answer:
A) The angles are 30-60-90. The longest leg (hypotenuse) of the triangle is twice the shortest leg. The middle leg is the shortest leg times the square root of 3.
Step-by-step explanation:
The answer choice speaks for itself.
The legs of a 45-45-90 triangle have the ratios 1 : 1 : √2.
The legs of a 30-60-90 triangle have the ratios 1 : √3 : 2.
Clearly, the given leg lengths match the second set of ratios more closely:
10 : 17.32 : 20 ≈ 1 : √3 : 2.
