Answer:
y²+10z-10y-yz
Reaaranging the terms
=y²-yz+10z-10y
taking common
=y(y-z)+10(y-z)
=(y+10)(y-z) is the right option
i hop this will help you :)
Answer:
She bought 24 Tangram puzzles
Step-by-step explanation:
Let the number of Tangram puzzles be t and the number of IQ puzzles be i
The sum of all the puzzles is 40;
i + t = 40 ••••••(i)
Cost of all Tangram puzzles at a cost of $4 per one will be;
4 * t = $4t
cost of all Iq puzzles at a cost of $2 per one is
2 * i = $2i
Sum
paid for all is $128
so;
4t + 2i = 128 •••••••(ii)
From equation i;
i = 40-t
Substitute into ii
4t + 2(40-t) = 128
4t + 80 - 2t = 128
2t = 128-80
2t = 48
t = 48/2
t = 24
Answer:
52° 86' 65"
Step-by-step explanation:
20° + 30° + 2° = 52°
15' + 41' + 30' = 86'
18" + 32" + 15" = 65"
X = 3 and CB = 19. To find x you would put 4x-9 + 3x+5 = 17. Remember to get all the x’s on one side and the other numbers on the other aide of the equal sign. Then plug x into the length of BC.
Step-by-step explanation:
,3^2+5^2=x^2
(3+5)^2=x^2
(8)^2=x^2
64=x^2
x=√64
X=8
