Answer:112 nectarines are needed.
Step-by-step explanation:
The math club is baking pies for a bake sale and they would require a number of peaches and nectarines
Let x represent the number of peaches.
Let y represent the number of peaches.
The fruit pie recipe calls for twice as many peaches as nectarines. This is expressed as
y = 2x
if it takes a total of 168 pieces of fruit for all the pies, it means that
x + y = 168 - - -- - - - - - 1
Substituting y = 2x into equation 1, it becomes
x + 2x = 168
3x = 168
x = 168/3 = 56
y = 2x
y = 2×56 = 112
A= 1/2(bh)
h=4b
50= (1/2)(b*4b)=2b^2
25=b^2
base = 5 that's your answer
height = 4xb = 4x5=20
12m²n² -8mn +1
[6mn-1]•[ 2mn-1]
[ 6mn•2mn + 6mn•-1 + -1•2mn +-1•-1]
= [ 12 m²n² -6mn -2mn +1]
= [ 12m²n2-8mn+1]

Answer:
All you need to do is plot it on a graph. DO it from least to greatest and do it in order
Step-by-step explanation:
Answer:
a = 5 1/3
Step-by-step explanation:
a+b+b = 24
a + 2b = 24
b-a =4
a = b - 4
b - 4 + 2b = 24
3b = 24 + 4
b =28/3
substitute this in a = b - 4
a = 28/3 - 4
a = 28/3 - 12/3
a = 16/3
a = 5 1/3
