Answer:
12 cm
Step-by-step explanation:
The formula for the area of a trapezoid is written as:
1/2(b1 + b2)h
h = height = 16 cm
b1 = Length of one parallel side = 9cm
b2 = Length of second parallel side = ?
Area of trapezoid = 168cm²
The formula to find the length of the second parallel side =
b2 = 2A/h - b1
b2 = 2 × 168/16 - 9
b2 = 336/16 - 9
b2 = 21 - 9
b2 = 12cm
Therefore, the length of the second parallel side is 12 cm
Answer:
289/216
Step-by-step explanation:
add the parentheses first
(2/3+3/4)×(3/6+4/9)=
17/12×17/18
then multiply
17/12×17/18=
286/216
Answer:
It is wrong because the answer should be way greater than the factors.
by the way the anwer is 6888
Step-by-step explanation:
The slope-intercept form for the line with slope -5 and y-intercept 3 is,
y= -3x+5.
What is the slope-intercept form of a line?
The conventional form Ax + By = C and y= mx + b have been used to describe linear equations. The slope-intercept form y = mx + b will now be the focus of our attention.
You can write a linear function using the slope of the line and the y-intercept in the slope-intercept form.
y=mx+b
Where b is the y-intercept and m is the slope.
A straight line's slope-intercept equation is written as y=mx+b, where m denotes the slope and b is the y-intercept.
In this case, m=3 and b=5 and y=3x+5 y=3x+5 is the necessary equation.
Hence,The slope-intercept form for the line with slope -5 and y-intercept 3 is,
y= -3x+5.
