Answer:
The difference between the area of the two circles is 15.7m
Step-by-step explanation:
I swear these be helping me with the CIEs coming up in May xD
Okay so the formula for a circle is 
The diameter is the double of the radius so
Cirlce A has a diameter of 4m so a radius of 2m
Circle B has a diameter of 6m so a radius of 3m
To find the difference subtract 12.57 from 28.27
The difference between the area of the two circles is 15.7m
Hope this helps, if you still need help just comment :)
Given slope = -4/3 and y-intercept = -3
Equation: y = -4/3x - 3
Answer:
k = -11
Step-by-step explanation:
Let 
And x+2 is a factor of p(x)
Let x+2 = 0 => x = -2
Putting in p(x)
=> p(-2) = 
<u><em>By remainder theorem, Remainder will be zero</em></u>
=> 0 = -8-6(4)-2k+10
=> 0 = -8-24+10-2k
=> 0 = -22-2k
=> -2k = 22
Dividing both sides by -2
=> k = -11

Answer:</h3>
- -100x +100; 3
- 5x +81; 162
<h3>
Step-by-step explanation:</h3>
The distributive property is your friend. It tells you ...
a(b + c) = ab + ac
It can also be used to simplify the product of binomials (or other polynomials).
(a +b)^2 = (a +b)(a +b) = a(a +b) + b(a +b) = a^2 +ab +ab +b^2
(a +b)^2 = a^2 +2ab + b^2 . . . . . . . worth remembering
1. (x -10)^2 -x(x +80) = (x^2 -20x +100) +(-x^2 -80x)
= -100x +100 . . . . . . simplified form
For the purposes of calculation, it can be easier to factor out 100:
= 100 (1 -x)
Then for x = 0.97
= 100(1 -0.97) = 100(0.03) = 3
___
2. (2x +9)^2 -x(4x +31) = (4x^2 +36x +81) -4x^2 -31x = 5x +81
For x = 16.2, this is ...
5(16.2) +81 = 81 +81 = 162
_____
The purpose of the attachment is to show the evaluation is correct.
30 × 100 = 3,000, 30 × 10³ = 30,000 and 30 × 1000 = 30000. Therefore, options A, B, C and D are the correct answers.
<h3>What is an equation?</h3>
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
A) 30 × 100 = 3,000
Here, LHS = RHS
B) 30 × 10³ = 30,000
Here, LHS = RHS
C) 30 × 1000 = 30000
Here, LHS = RHS
D) 
30 × 10000 = 300,000
Here, LHS ≠ RHS
E) 30 × 10000 = 30,000
= 300,000
Here, LHS ≠ RHS
Therefore, options A, B, C and D are the correct answers.
