The standard size of the rectangle's area is x² + 12x + 35
Given:
a diagram that depicts the polynomial that denotes a rectangle's length and width.
The rectangle's area is equal to its length x width.
Given that length is equal to x + 7 and width is equal to x + 5, the area is equal to length plus width.
Add the numbers in brackets: Area = x2 + 5x + 7x + 35
Area = x2 + 12x + 35
A quadrilateral with equal angles and parallel opposite sides is referred to as a rectangle. We are surrounded by numerous rectangular objects. The length and width of a rectangular shape are the two dimensions that define it. The rectangle's length and width are its longer and shorter sides, respectively. We will learn about the properties of the rectangle shape in this chapter.

Full Question = Express the area of the entire rectangle.
Your answer should be a polynomial in standard form.
x+7 x+5
Answer:
Cos a = 3/8.
Step-by-step explanation:
If you want cos a you use the identity cos a = 1 / sec a,
so cos a = 1 / 8/3
= 3/8.
Answer: 
Step-by-step explanation:
The formula we need to use is:
We know that "T" is the total time for driving and hiking and "x" is the average velocity on the hike.
Knowing that the tourist drives 70 miles along the scenic highway and walk 7-mile walk along the hiking trail, and also knowing that the average velocity driving is 7 times that while hiking, we can conclude that the total time is:
Finally, simplifying the equation, we get that the total time for driving and hiking as a function of the average velocity on the hike, is:
Answer:
x = 9
m Angle B = 54
m Angle E = 54
Step-by-step explanation:
As m Angle B and m Angle E are congruent,
5x + 9 = 7x - 9
-2x = - 18
x = 9
m Angle B = 5x + 9 = 54
m Angle B = m Angle E
Therefore, m Angle E = 54
