Answer:
C
Step-by-step explanation:
P= side 1+ side 2 + side 3
40-(17+8)=15
15x8/2=60
Area of triangle, who has perimeter of 40 centimeters is 60 cm².
What is Area of Triangle?Area of a Triangle = A = ½ (b × h) square units
where b and h are the base and height of the triangle, respectively.
Given: Perimeter= 40cm
Now, 17+8+side=40
side= 40-25
side= 15 cm
Now, Area of triangle,
=1/2*b*h
= 0.5*15*8
= 60 cm²
Hence, Area of triangle= 60 cm².

5 (2 x + 4) + 25 x = 2.65
0.05 (2 x + 4) + 0.25 x = 2.65
0.5 (2 x + 4) + 0.25 x = 2.65
(2 x + 4) + x = 2.65
Answer:
0.05(2x +4) +0.25x =2.65
Step-by-step explanation:
The decimals are in the right places. A. would have been correct but it would have had to be 265 instead of 2.65. They put the decimals in the incorrect place.

profit p(x) is the difference between revenue…
Answer:
x^4-3x^3+x^2-4
mrk me brainliest plz
Step-by-step explanation:
Given the following functions
R(x) = 2x^4 – 3x^3 + 2x – 1 and
C(x) = x^4 – x^2 + 2x + 3
We are to find the profit function P(x)
P(x) = R(x) - C(x)
P(x) = 2x^4 – 3x^3 + 2x – 1 - ( x^4 – x^2 + 2x + 3)
P(x) = 2x^4 – 3x^3 + 2x – 1 - x^4 + x^2 - 2x - 3
Collect the like terms
P(x) = 2x^4-x^4-3x^3+x^2+2x-2x-1-3
P(x) = x^4-3x^3+x^2+0-4
P(x) = x^4-3x^3+x^2-4
Hence the required profit function P(x) is x^4-3x^3+x^2-4
Answer:
i think its x^4-3x^3+x^2-4

6x +
x = [?]
Enter
Answer:
Step-by-step explanation:
you know some things about the two angles they are the complimentary parts of just one of those perpendicular lines. so you can say
180 = (6x + 5) + (3x+13)
180 = 9x +18
162 = 9x
18 = x
Answer:
Solution given;
6x+5+3x+13=180(sum of exterior angle is 180°)
9x=180-18
x=162/9
x=18 is a required answer.

find perimeter of each polygon. Assume that the lines which appear to be tangent are tangent. Part 1. NO LINKS OF ANY KIND.
9514 1404 393
Answer:
7) 57.8
8) 73.8
Step-by-step explanation:
The tangents from a given point are the same length. This means the perimeter can be calculated as twice the length of one side plus twice the length of an opposite tangent.
7) P = 2(22.2 +6.7) = 57.8
8) P = 2(22.9 +14) = 73.8
