To solve this problem you must apply the proccedure shown below:
1. Yoy have that the <span>rectangular tank has the following dimensions:
Length=3 inches
Widht=4 inches
Height=5 inches
2. Then, its volume is:
V1=LxWxH
V1=3 inchesx4 inchesx5 inches
V=60 inches</span>³
3. The sides of the <span>solid metal cube are of 3 inches, therefore, its volume is:
V2=s</span>³
V2=(3 inches)³
V2=27 inches³
4. T<span>he volume, in cubic inches, of water that the tank can now hold is:
Vt=V1-V2
Vt=60 inches</span>³-27 inches³
Vt=33 inches³
According to the solving the perimeter of the given triangle is:
= -x³ + 13x² + 11x + 20
<h3>Describe the triangle:</h3>
Three edges and three vertices make up a triangle, which is a polygon. It is among the fundamental shapes in geometry. Triangle ABC refers to a triangle with the vertices A, B, and C. In Euclidean geometry, any three points that are not collinear determine a singular triangle and a singular plane at the same time.
<h3>What is the formula for the triangle's perimeter?</h3>
Simply summing the lengths of all the sides of a triangle yields its perimeter. A + B + C is the basic formula to determine the perimeter of a triangle with sides "a," "b," and "c."
<h3>According to the given data:</h3>
A = 9x+10x²-x³
B = -x² + 9x + 12
C = 4x²-7x+8
We know that the perimeter of the triangle is sum of all side of the triangle:
A+B+C
= (9x+10x²-x³) + (-x² + 9x + 12)+(4x²-7x+8)
= -x³ + 13x² + 11x + 20

Answer:

Step-by-step explanation:
x - 5 - 3x + 1 = -45
-2x - 4 = -45
-2x = -45 + 4
-2x = -41
x = 41 ÷ 2
x = 41/2
