Answer:
Surface area means all 6 sides
TOP side= 2 multiplied by 5
Bottom = 2 multiplied by 5
Right face = 2 multiplied by 8.1
Left face = 2 multiplied by 8.1
Back side = 5 multiplied by 8.1
front side = 5 multiplied by 8.1
10+10+16.2+16.2+40.5+40.5 = 133.4 cm ^2
Short leg = 18 Long leg= 24 Hypotenuse= 30
My calculations were simple trial and error. I started with a trial of 10 for the short leg to begin with, averaging and estimating the appropriate proportions based off 6 additional increments. Sorry I don't have an algebraic method for you. Hope this has helped somewhat :)
-15
8-23=-15
To check
-15+23=8
Answer:
5 2/3
Step-by-step explanation:
First add the whole numbers (3+2 = 5).
Then add the fractions. Since they already have common denominators, just add the numerators (1+1 = 2) and the denominator stays the same.
Since the numerator (top of the fraction) is smaller than the denominator (bottom of the fraction) and it can't be simplified, we are done. :-)
Answer:
x = 5
Step-by-step explanation:
-4x - 2 = -22
-4x = -22 + 2
-4x = -20
x = -20 / -4
x = 20 / 4
x = 5
