What is this I can’t read it
Answer:
3
Step-by-step explanation:
Since we already know c, so we need to find b.
c² = a² + b²
5² = 4² + b²
b² = 5² - 4²
b² = 25 - 16
b² = 9
b = 3
Answer:
C
Step-by-step explanation:
y=5x reads "y equals (5 times x)", which we can rephrase to "the value of y is 5 times the value of x"
y=x+5 reads "y equals (x plus 5)", which we can rephrase to "the value of y is 5 more than the value of x".
Ergo, answer C is what we're looking for.
The error occurred on step 1 (i highlighted it)
2 x 2 x 2 equals 8. Cubed means to multiply 2 by 2 3 times, 2 x 2 = 4, x 2 = 8.
