Answer:
8 bracelets
Step-by-step explanation:
Given
Yellow = 40 beads
Red = 64 beads
Required
Highest number of bracelets
To answer this question, we simply need to determine the highest common factor of the given parameters.
40 = 2³ * 5
64 = 2⁶
HCF = 2³
HCF = 2 * 2 * 2
HCF = 8
Hence, the maximum number of bracelets is 8
Answer:
12 miles by 8 miles
Step-by-step explanation:
Let length be represented by x
Since width is 4 miles less than the length, therefore, the width will be (x-4) miles
Area=Length*Width
Area=x(x-4)=
Area is given hence

To write the above equation as a quadratic equation

By factorization, we find two numbers whose sum is -4 and product is -96, these are 8 and -12. Therefore, taking these two numbers back to our equation
(x+8)(x-12)=0
Therefore, x=-8 or 12
Equally, using quadratic formula of
for equation
and in our case a=1, b=-4 and c=-96

x=-8 or 12
Since length can't be negative, hence x=12
The length is 12 miles
Width=12-4=8 miles
Dimensions: 12 miles by 8 miles
Ok so... what wait weres the pic??
Answer:
1. In the multiplication of the imaginary parts, the student forgot to square of i. OR
2. The student has only multiplied the real parts and the imaginary parts.
Correct value
.
Step-by-step explanation:
The given expression is

A student multiplies (4+5i) (3-2i) incorrectly and obtains 12-10i.
Student's mistake can be either 1 or second:
1. In the multiplication of the imaginary parts, the student forgot to square of i.
2. The student has only multiplied the real parts and the imaginary parts.

Which is not correct. The correct steps are shown below.
Using distributive property, we get



![[\because i^2=-1]](https://tex.z-dn.net/?f=%5B%5Cbecause%20i%5E2%3D-1%5D)


Therefore, the correct value of
is
