H = height of triangle
b = length of triangle base
A = area of triangle
Recall the formula for area of a triangle :
A = 1/2 bh
Plug in what was given in the problem :
h = b - 5
A = 42
A = 1/2 bh
42 = 1/2 b (b-5)
Answer: what do you need
Step-by-step explanation:
Answer:
D. on the x axis is the best answer
Answer:
C
Step-by-step explanation:
Using PEMDAS we can figure out what to do to simplify this problem.
The "E" in PEMDAS referrers to "Exponents".
Square roots are still exponents, just written weird.
So, according to the laws of PEMDAS, we must find the square root of 38 first
Next, we just add 2.
6.16 + 2 = 8.16
Point C is the closest to 8.16
