Answer:
y= -7
Step-by-step explanation:
So first distribute the 8
4=8y+32-4y
now combine like terms (the -4y+8y)
4=32+4y
Subtract 32 on both sides to isolate 4y
-28=4y
now divide 4 on both sides to isolate Y
-7=y
so y= -7
The formula for converting Fahrenheit to Celsius is:
~Multiply by 1.8 (or 9/5) and add 32.
Hope this helps!!!
Ok so material needed=surface area
SA=2(LW+LH+WH)
note: LW means legnth times width
so
first box is
8 inches by 6.25 by 10.5
assign them
8=legnth
6.25=width
height=10.5
SA=2(8 times 6.25+8 times 10.5+6.25 times 10.5)
SA=2(50+84+65.625)
SA=2(199.625)
SA=399.25
second box
9 by 5.5 by 11.75
L=9
W=5.5
H=11.75
SA=2(9 times 5.5+9 times 11.75+5.5 times 11.75)
SA=2(49.5+105.75+64.625)
SA=2(219.875)
SA=439.75
so we now have
first box=399.25 in^2
second box=439.75 in^2
439.75>399.25
second box needs more material
Answer:
16y + 32
Step-by-step explanation:
Expand each term.
(y+6)² - (y-2)²
= (y+6)(y+6) - (y-2)(y-2)
= y² + 12y + 36 - (y² - 4y + 4)
Subtract the second group by changing each term's signs
= y² + 12y + 36 - y² + 4y - 4
Collect like terms
= 16y + 32
