Step-by-step explanation:
the lengths of any line (side, height,...) in A is twice as long as in B.
now, the area of a triangle is
baseline × height / 2
so, two lines are multiplied. that means the factor 2 gets multiplied in 2 times. and that means the area increases by the factor 2×2 = 4
therefore, the area of A is
40.5 × 4 = 162 cm²
Answer:
x=4
Step-by-step explanation:
12 * X+3=51
Subtract 3 from each side
12x +3-3 = 51-3
12x = 48
Divide by 12
12x/12 = 48/12
x = 4
Answer:
A) -15, 5, 2
Step-by-step explanation:
Hello!
First you have to find what the outlier is
Since 55 if a number way higher than the rest of the data it is the outlier
Removing the outlier does not change the mode
Now we look at what the median is without the 55
The median is 40 when we remove the 55
The answer is A
Hope this helps!
