We know that the perimeter of a rectangle can be represented by the expression 2l +2w, where l represents the length of the rectangle and w represents the width of the rectangle.
If we substitute in the values given in this problem, we get the expression:
2(2x+6) + 2(x)
Another equivalent expression we can use to express the perimeter is w + w + l + l.
If we substitute in the values given in this problem into this expression, we get:
x + x + 2x + 6 + 2x + 6
Overall, we know that these expressions are equivalent and represent the same value (the perimeter of the rectangle), because if you combine like terms, both expressions simplify to 6x + 12.
Hope this helps!
Answer:
112ft^2
Step-by-step explanation:
A = 2(wl+hl+hw)
A = 2[(4)(8)+(2)(4)+(2)(8)]
A = 2(32+8+16)
A = 2(56)
A = 112
Answer:
look below
Step-by-step explanation:
The answer is not correct because the dot on -9 should be unshaded. When dealing with signs with the equal sign on the bottom you leave it shaded, but if it has no equal sign you leave it unshaded. It is pointing in the correct direction which is left as we know - 10,-11, and -12 are less than -9.
Answer:
x= 2,4,6,8.......any even number
Step-by-step explanation:
Perimeter is 4+4 + 3x+3x = 8+6x
The result of 8 + 6 times a number should be a multiple of 4.
PERIMETER AREA
8+(6*2)= 8+ 12 = 4*5=20
8+(6*4) = 8 +24=32 4*8=32
8+(6*6) =8+36 =44 4*11=44
8+(6*8)=8+48=56 4*14=56
And so on.......
<span>cos x = [ e^(ix) - e^(-ix) ] / 2i along with [ A - B ]^5 =
( A^5 - B^5) - 5 AB ( A^3 - B^3) + 10 A²B² (A - B )...A = e^(ix) , B = e^(-ix)
[ cos x ] ^5 = (1/32i) { [ e^(5ix) - e^(-5x) ] - 5 [ ( e^(3ix) - e^(-3ix) ] + 10 [ e^(ix) - e^(-ix) ] }
= ( 1 / 16 ) { cos 5x - 5 cos 3x + 10 cos x }.....much faster</span>
