<em>Comment on the squaring</em>
There are several ways you can find the square (x+4)².
- Use your knowledge that (x+a)² = x²+2ax+a².
- Use FOIL* to compute (x+4)(x+4) = x² +4x +4x +4² = x²+8x+16
- Use the distributive property: (x+4)(x+4) = x(x+4) +4(x+4) = x² +4x +4x +4² (same as FOIL for two binomials)
__
* FOIL is mnemonic for {First, Outer, Inner, Last} referring to pairs of terms in the factors (x +a)(x +b). The x terms are the First terms. The Outer terms are the first x and b. The Inner terms are "a" and the second x. The Last terms are "a" and "b". You are to form the sum of those pairs of terms to find the product of the binomials.
Answer:
Step-by-step explanation:
Given:
Radius of circular mirror, r = 6x
Length of metal frame, l = 18x
Area of square, As = l^2
Area of square = 18x × 18x
= 324 x^2.
Area of circular mirror, Ac = pi × r^2
= π × (6x)^2
= 36π x^2.
The expression for the area of the frame is subtracting the mirror from the metal frame = As - Ac
= 324x^2 - 36πx^2
= 36x2 (9 - π).
I believe the answer is 4 if you need an explanation then reply to me!
2 combines = 320 acres
320/2 = 160 acres per combine
160 * 6 = 960
Answer: 960 acres
Hope this helps!
Answer:
Given the expression: 
Let the value of the given expression in radians be 
then;
......[1]
We know the value of 
Substitute the given value in [1] we have;
Since, the value of 
is 0, therefore, the value of is in the form of:
; where n is the integer.
At n =0, 1 and 2, {Since, n is the integer}
Value of 
and 
therefore, the answer in radians either 
or
