If two shapes are similar, they are scaled by some factor. In other words, you have
In particular, we know that
And we deduce
So, the perimeter of ABC is
So, the perimeter of ABC is three times the perimeter of DEF, and thus it's
feets
I think is Y=5x+20
Hope you get it right!

Answer:
17
Step-by-step explanation:
Now it says the number is 68 less than 5 times a number. x=68. Thus the number will be 17.
Answer: A
Step-by-step explanation:
Power rule: derivative of x^(something) is (something)* x (something -1). Rewrite the second term as x^(-7) and it all becomes -3x^(-3-1) + (-7)x^(-7-1). Rest is just writing it in a "nicer" form
The expression 4x^2-px-7 leaves a remainder of -2 when divided by (x-3). Then the value of p is 10.33
<h3><u>
Solution:</u></h3>
Given the expression is leaves a remainder of -2 when divided by (x-3)
To find: value of p
x - 3 = 0
x = 3
Let
Hence we can say,
g(3) = -2
Substitute x = 3 in g(x) we get,
On solving we get,
-2 = 4(9) - 3p - 7
-2 = 36 - 3p - 7
3p = 36 - 7 + 2
3p = 31
Thus the value of p is 10.33
