Answer:
The ratio of the areas will be will be 1 : 9
Step-by-step explanation:
The linear scale factor represents a ratio that is used to multiply the dimensions of objects so that accurate geometries can be transferred between real-life and paper.
The linear scale factor is quite different from the area scale factor but related to it in the following way:
The area factor can be obtained by squaring the linear scale factor.
This is Area factor = (Linear scale factor) ^2.
Linear scale factor = (1:3)
Area factor = 
Area factor will be 1: 9
Thus, when the linear scale factor is 1:3 the area factor will be 1 : 9
Answer:
m<B: 56
Step-by-step explanation:
All triangles add up to 180
<B = x
x + 34 + 90 = 180
x + 124 = 180
x = 56
<span>Simplifying
(x + 3)(x + 2)
Reorder the terms:
(3 + x)(x + 2)
Reorder the terms:
(3 + x)(2 + x)
Multiply (3 + x) * (2 + x)
(3(2 + x) + x(2 + x))
((2 * 3 + x * 3) + x(2 + x))
((6 + 3x) + x(2 + x))
(6 + 3x + (2 * x + x * x))
(6 + 3x + (2x + x2))
Combine like terms: 3x + 2x = 5x
(6 + 5x + x2)
Factor a trinomial.
(3 + x)(2 + x)
Final result:
(3 + x)(2 + x)</span>
Remember that scientific notation always contains a number between 0 and 10 that is multiplied by ten to some power. In this case, to get a number between 0 and 10 (7.2) we would move the decimal point once to the right. Since it is moving to ththe right, the exponent over the 10 will be negative, and it will be -1 because we moved the point once. So the answer is 7.2*10^-1
