Answer:
30.5
Step-by-step explanation:
We know that ABCD is similar to EFGH so that means you can use a scale factor for them to figure out the rest of the side lengths.
25/12.5=2
12/6=2
Therefore the scale factor is two. Then we can use the numbers from the other side lengths which are 12 and divide by 2. Which gets you 6 for each remainder of the sides.
Then add them
12.5+6+6+6 = 30.5
P= 30.5

Expand the second and 3rd factors first. Then worry about the x.
Solution
x(x + 2)(x + 4)
<em>first</em>: x * x = x^2
<em>Outside</em>: 4*x = 4x
<em>Inside</em>: 2*x = 2x
<em>Last:</em> 2*4 = 8
Combine
x^2 + 4x + 2x + 8
x^2 + 6x + 8
Now is the time to worry about the extra x
x(x^2 + 6x + 8)
remove the brackets.
x*x^2 + x*6x + 8*x
Combine
Answer: x^3 + 6x^2 + 8x
It is equivalent to 16 cm
Answer:
-5
Step-by-step explanation:
y intercept occurs when x = 0
f(0) = -4(0)² + 2(0) - 5
f(0) = - 5
Answer:
The answer is 16
Step-by-step explanation:
8 divided by 2 (2+2)=16
