Answer:224.0526316 and it just keeps going on
Step-by-step explanation:
Answer:
n = 24
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= =
hence
= ( cross- multiply )
35n = 30 × 28 = 840 ( divide both sides by 35 )
n = = 24
The answer for S will be 49/4.
Remark
The area = 4*(x + 3) to start with. If you remove the brackets,
A = 4(x + 3)
A = 4*x + 3*4
A = 4x + 12 <<<<<< Answer for A
Part B
The area will become 4 times larger.
A = 4*(4x + 12)
A = 16x + 48
Argument
You may not be wholly satisfied with an unproved statement. I could prove it with algebra but it might be easier just to give an example.
Area = L * W
L = 10
W = 5
Area = 10*5
Area = 50
Now double both L and W
L = 20
W = 10
Area = L*W
Area = 20*10
Area = 200 which is 4 times the size of 50.
Answer:
f(-1)=3
Step-by-step explanation:
f(x)=x^2-6x+3x-1
f(x)=x^2-3x-1
f(-1)=(-1)^2-3(-1)-1
f(-1)=1+3-1
f(-1)=4-1
f(-1)=3
