Step-by-step explanation:
Build a rectangle 12 cm high and 5 cm wide (Paint it). Then a) Find the perimeter of the rectangle. B) Find the area of the rectangle. Aiuda porfis.
Length of the rectangle is 12 cm
Breadth of the rectangle is 5 cm
Perimeter is the sum of all sides. For rectangle it is given by :
P = 2(l+b)
⇒ P=2(12+5)
P = 34 cm
Area of a rectangle is equal to the product of its length and breadth.
So,
A = lb
A = 12 cm × 5 cm
⇒A = 60 cm²
Hence, perimeter is 34 cm and area of rectangle is 60 cm².
Answer:
$0.25+$0.05+$0.03=$0.33
$0.33•6=$1.98
$1.98+$4.87=$6.85
Step-by-step explanation:
Answer:
A) x = (-8log(6)-2log(17))/(-2log(17)+log(6))
Step-by-step explanation:
Taking the logarithm of the equation, you have ...
(x+8)log(6) = (2x-2)log(17)
Subtracting the right side from the equation gives ...
x(log(6) -2log(17)) +8log(6)+2log(17) = 0
Subtracting the constant and dividing by the coefficient of x gives ...
x = -(8log(6) +2log(17))/(log(6) -2log(17)) . . . . . matches selection A
___
You don't need to work out the whole solution to determine the correct answer choice. Once you take the initial log, you find that the x-coefficient includes a multiplier of 2log(17). This term only appears in the denominator of choice A. (The value of x will be found after dividing by the x-coefficient, so you know this must show up in the denominator of the answer.)
I guess this how it would go
<span><span><span>(5)</span><span>(<span>−2</span>)</span></span>−<span><span>(2)</span><span>(<span>−3</span>)</span></span></span>
So your answer should be <span>−4</span>
Step-by-step explanation:
Simplify the left side:
5x - 20 = 3x + 4
Move all terms containing x to the left side of the equation:
2x - 20 = 4
Move all terms not containing x to the right side of the equation:
2x = 24
Divide each term by 2 and simplify:
x = 12
