Here, hopefully this picture cane help
Answer:
A
Step-by-step explanation:
Area of a base: 16 × 15 ÷ 2 = 120
Area of sides:
37 × 15 = 555
37 × 16 = 592
37 × 20 = 740
Area of prism: 2 × 120 + 555 + 592 + 740 = 2127
The slope of the line <span>x=1</span><span> does not exist. Because there are no tow points with different </span>x<span> values on the line.</span>
It is not defined.
<span>This case is not includes in the definition of slope.</span>
a) All three athletes accelerated because the slope of every line in the beginning in positive.
b) Dash decelerated towards the end because the slope of the line representing him becomes negative.
c) Flash maintained a constant speed because the slope of his line does not change.
d) Krash's line is horizontal because he did not move for that time.
e) Flash won the race because his line reaches 100 first.
First, write an equation system based on the problem
An equation for "the perimeter of a rectangle is 70 in" can be written as following
∴ 2l + 2w = 70 <em>(first equation)</em>
An equation for "the length is 11 in more than its width" can be written as following
∴ l = w + 11 <em>(second equation)</em>
Second, solve the equation by substitution method o find the dimension of the rectangle.
Substitute/plug l as (w+11) into the first equation
2l + 2w = 70
2(w + 11) + 2w = 70
2w + 22 + 2w = 70
4w + 22 = 70
4w = 70 - 22
4w = 48
w = 48/4
w = 12
The width of the rectangle is 12 in
Substitute w with 12 to the second equation
l = w + 11
l = 12 + 11
l = 23
The length of the rectangle is 23 in
Third, find the area of the rectangle
a = l × w
a = 23 × 12
a = 276
The area of the rectangle is 276 in²
