Answer:
Yes, you can find the cube root of a negative number. The answer will be negative!
Step-by-step explanation:
Example: Find the cube root of -27
We know that a cube root is a number multiplied by itself 3 times (NOT MEANING THE NUMBER TIMES 3)
For example, The cube root of 27 positive is 3 because 3 x 3 x 3 = 27
But if we are using a negative number: It is really different because we got to know the rules.
The setup: -3 x -3 x -3 = -27
If we started with -3 x -3 first we know that a negative times a negative equals positive so the answer will be 9 positive, then we have this equation left:
9 x -3 = -27
The rule with this is a number times a negative is negative, so the answer of the question "Find the cube root of -27 is -3"
Answer:
A. 29
B. 11
C. 10
D. 12
Step-by-step explanation:
A. 180 - 122 = 58
58 divided by 2 = 29
-
B. 180 - 37 = 143
x = 11
5 x 11 = 55
8 x 11 = 88
55 + 88 = 143 + 37 - 180
-
C. the small box in a triangle means right angle = 90
90 - 68 = 22
(2x - 2) we subtract before finding out what x is
22 - 2 = 20
2x = 20 divide by 2 = 10
x is equal to 10
-
D. to find the total, you must figure out what each equation is to add them up to make 180.
(8x + 3) + (2x + 9) + 4x = 180
add up the numbers with x and the numbers without them
14x + 12 = 180
subtract 180 - 12 = 168
168 divided by 14 = 12
x = 12
Hope this helped !!
Answer:
I believe the correct answer would be the last one.
Step-by-step explanation:
The units are supposed to be blocked by gender. However, the first two units in the final option are blocked with two females in one group, and two males in the next. This is inconsistent with the blocking method used for the rest of the units.
