<span>A. The perimeter, P, of a rectangle is the sum of twice the length and twice the width.
answer
1. P = 2(l+w) units
</span><span>2. P = 2(5)+2(9) units
</span><span>4. P = (l+l)+(w+w) units
</span><span>B. The area, A, of a triangle is one-half the product of the triangle's base and height.
</span>answer<span>
2. A = 1/2(12)(5)
3. A = 1/2(b*h)
</span>
W and V are corresponding as well as X and Y
your answer is A
you can tell by the amount of lines in each angle :)
Answer:
15 i
Step-by-step explanation: Anytime a number is negative and you have to find the square root there is always going to be an i at the end of it so it would only be 15 i in this case
Answer:
s = 2x²+3x-23
Step-by-step explanation:
Given that,
First side of a triangle = 3x+8
Second side of a triangle = 2x²-4x+5
The perimeter of the triangle = 4x²+2x-10
We need to find the expression for the third side. Let the third side b s.
Perimeter = Sum of all sides
4x²+2x-10 = 3x+8 + 2x²-4x+5 +s
4x²+2x-10 = 2x²-x+13+s
s = 4x²+2x-10- (2x²-x+13)
= 2x²+3x-23
So, the third side will be 2x²+3x-23.
