Answer:
(4,-6)
Step-by-step explanation:
Answer: m = 9 .
_________________________________________
Explanation:
_________________________________________
Given: (3 ¾) m = (33 <span>¾) ; Solve for "m" ;
</span>_________________________________________
Method 1):
Rewrite the fractions in "decimal form"; and rewrite the equation:
_____________________________________________
(3.75) m = 33.75 ;
Divide each side of the equation by: "(3.75)" ;
to isolate "m" on one side of the equation; and to solve for "m" ;
____________________________________________________
(3.75) m / 3.75 = 33.75 / 3.75 ;
____________________________________________________
m = 33.75 / 3.75 ;
m = 9 .
____________________________________________________
Method 2):
___________________________________________________
Rewrite the fractions as improper fractions:
____________________________________
3 ¾ = [ (4*3) + 3 ] / 4 = (12 + 3) / 4 = 15/4 ;
33 ¾ = [ (4*33) + 3 ] / 4 = (132 + 3) / 4 = 135/4 ;
_______________________________________________
And rewrite the equation:
_______________________________________________
(15/4)m = (135/4) ;
_______________________________________________
→ Multiply the entire equation (both sides) by "4" to eliminate the fractions ;
_______________________________________________
→ 4 * (15/4)m = 4 * (135/4) ;
→ All the "4's" on BOTH sides "cancel out" to "1" ;
and we are left with:
_______________________________________________
→ 15 m = 135 ;
_______________________________________________
Now, divide EACH side of the equation by "15" ; to isolate "m" on one side of the equation; and to solve for "m" ;
_______________________________________________
→ 15 m / 15 = 135 / 15 ;
_______________________________________________
→ to get: m = 9 .
_______________________________________________
Method 3):
______________________________________________
Similar to "(Method 2)" directly above, except the step at which we get to:
________________________________________
→ (15/4)m = (135/4) ;
________________________________________
Instead of multiplying each side of the equation by "4" ;
We divide EACH side of the equation by "(15/4)" ; to isolate "m" on one side of the equation; and to solve for "m" ;
__________________________________________
→ (15/4)m / (15/4) = (135/4) / (15/4)
= (135/4) ÷ (15/4) = (135/4) * (4/15)
= (135*4) / (15*4) = (540) / (60) = 54/6 = 9 .

Find the S.A of all the cubes and then add them together.
S.A = 6a²
a is the side length
S.A = 6(3)² = 54
S.A = 6(2)² = 24
S.A = 6(1)² = 6
Now add them all together.
54 + 24 + 6 = 84
So the total surface area is 84
Hope this helps :)
