Answer:
Area: 5x + 10
Perimeter: 2x + 14
Step-by-step explanation:
Area = length times width
Perimeter = length (2) + width (2)
<u>Area:</u>
Multiply the length be the width. That gives you 5 (x + 2).
Then use the distributive property to simplify this expression. That gives you 5x + 10.
<u>Perimeter:</u>
Multiply the width by 2. That gives you 10.
Multiply the length by 2. That gives you 2x + 4
Add the 2 together. That gives you 10 + 2x + 4.
Combine all like terms. That gives you 2x + 14.
Answer:
I think the answer is 1
Step-by-step explanation:
-(-2)-1
=1
1. --> d
2. --> b
3. --> a
4. --> c
1 is d because that is the only piece of information that sounds like a given.
2 is b because we know that from the given, m∠1 is complementary to m∠2 and in the first problem, m∠1 + m∠2 = 90, they are added together. The definition of complementary angles is "Two angles with measures that, when added together, equal 90 degrees". Same thing with m∠3 and m∠2.
3 is a because since both of the problems equal 90 degrees, you can just take away the 90 and put an equal sign in between the two problems because they equal the same thing.
4 is c because you are subtracting m∠2 from the problems and ending up with just m∠1 = m∠3.
Hope this helps! :)
The roots of a polynomial are the values that render the polynomial to zero
y=(x+4)(x-2)^2(x+7)
in the 1st parenthesis, x=-4 render the polynomial =0
in the 2nd parenthesis, x=2 render the polynomial =0
in the 3rd parenthesis, x=-7 render the polynomial =0
So there are 3 values as roots of this polynomial (answer C)
Using the distance formula, when I plugged in the information, the answer I got was the square root of 85. (B)
