The answer to the equation is approximately 536.91
Answer:
462 
Step-by-step explanation:
Rectangular Prism: 7 x 8 x 6 = 336
Triangular Prism: (0.5 x 7 x 6) x 6 = 126
336 + 126 = 462
Answer:
Hi there!
Your answer is;
the equation
(w+6)+(w+6)+(w)+(w) = 52
The width of this rectangle is 10. The length of this rectangle is 16.
Step-by-step explanation:
Rectangular perimeter:
l+l+w+w
l= w+6
w= w
(w+6)+(w+6)+(w)+(w)
4w+12= 52
4w = 40
/4
w= 10
Hope this helps!
Answer:
6m²
Step-by-step explanation:
Because the question asks for the area of a face but it doesn't indicate which face then it can be any of the faces.
2m x 3m = 6m²
2m x 4m = 8m²
3m x 4m = 12m²
In your case one of the possible answers is 6m² - so that is the one they are looking for.
So you subtitute y=3x into
2x+y=15
so
2x+(3x)=15
add like terms
5x=15
divide both sides by 5
x=3
subtitute x=3 into first equation (y=3x)
y=3(3)
y=9
