The distance between points (1, 1) and (4, 7) is 6.71. is it true or false

svet-max [94.6K]

To determine whether the statement is true or false, we need to calculate for the distance of the two points. To do this, we can use the pythagorean theorem as follows:

d = √[(y2-y1)^2 + (x2-x1)^2]
d = √[(7-1)^2 + (4-1)^2]
d = √[(6)^2 + (3)^2]
d = 2√13 = 7.21

Therefore, the statement is false.

Hugo is designing a frame as shown at the right. The frame has a width of x inches all the way around. Write. an expression that

Cloud [144]

The expression which shows the total area of the picture and frame is $x^{2} +72x$ +320.

Given that the width of the frame is x ,length horizontally be 20 inches and vertically be 16 inches.

We are required to find the expression which shows the total area of the picture and frame.

Expression is basically a combination of numbers, symbols, coefficients, determinants, indeterminants,etc. and are mostly not found in equal to form.

Since we are given that the width of the frame be x, So,the are of only frame will be :

Area of frame=20*x*2+16*x*2+x*x

=40x+32x+ $x^{2}$
