Answer:
<u>u=5</u>
Step-by-step explanation:
(u-3)2+2(u-3)-8=0
2u-6+2u-6-8=0
4u-20=0
4u=20
u=5
Answer:
-3/4
Step-by-step explanation:
y-y on top in the numerator
x-x on the bottom in the denominator
y= (-2-(-11))= 9
x= ( -4-8)= -12
answer is -9 over 12 or reduced to -3 over 4
Answer: Let x = number of pounds of jelly beans
y = number of pounds of almonds.
Then, 4x + 8y = 33
2x + 3y = 13
Multiply the second equation by -2 to get the system:
4x + 8y = 33
-4x - 6y = -26
Adding the equations, we get 2y = 7. So, y = 3.5
Substitute for y in either of the given equations: 2x + 3(3.5) = 13
2x + 10.5 = 13
2x = 2.5
x = 1.25
ANSWER: a pound of jelly beans costs $1.25 and a pound of almonds costs $3.50.

Answer:
<u>3</u><u>6</u><u>cm</u>
Step-by-step explanation:
2l + 25
l=14cm, w= 4cm
2(14cm+4cm)=
28cm + 8cm=
<u>36cm</u>
It should be d! Hope this helps! sorry if I'm wrong!
