Eth enlarged the triangle below by a scale of 5.

A triangle with a base of 4 centimeters and height of 3.5 centimeters.

She found the area of the enlarged triangle. Her work is shown below.

One-half (4) (3.5) (5) = 35 centimeters squared

What was Beth’s error?

She should have divided One-half (4) (3.5) by 5.

She should have divided One-half (4) (3.5) by 5 squared.

She should have multiplied (4) (3.5) by 5.

She should have multiplied One-half (4) (3.5) by 5 squared.

She should have multiplied one half (4)(3.5) by 5 squared.

Step-by-step explanation:

We are given that

Base of triangle=b=4 cm

Height of triangle=h=3.5 cm

Area of triangle=

After enlarged

Scale factor=5

New base of enlarged triangle=b'=4(5) cm

Height of enlarged triangle=h'=3.5(5) cm

Area of enlarged triangle=

But Beth wrote

Area of enlarged triangle=

She should have multiplied one half (4)(3.5) by 5 squared.

d

step-by-step explanation:

i used the pitagoras theoreme

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
