Answer:
<B = 70°
Step-by-step explanation:
First we need to find x, lets plugin these two equations.
2x - 30 = x + 20
Then find like terms
2x = x + 50 =
x = 50
Then we plugin 50 for x
2(50) - 30 =
100 - 30 = 70
<B = 70°

Answer: Statement B in the lower left corner</h3>
When you raise an exponential expression to another exponent, you multiply the exponents. We have 8*5 = 40 as the final exponent. The rule is (x^y)^z = x^(y*z). The base stays the same.
Statement A is not true because we should be adding the exponents. The rule is x^y*x^z = x^(y+z). Note how the bases are all the same. We'll use this rule for statement C to show that it is also false.
A similar rule is (x^y)/(x^z) = x^(y-z). We subtract the exponents this time. This rule is used to show that statement D is false.
The greater the absolute value of the slope, the steeper the line.
Therefore, slope of -3 represents the steepest line.
The areas of the two parallelograms are 105 square inches and 20.997 square yards, respectively.
<h3>How to determine the area of a parallelogram</h3>
A parallelogram is a quadrilateral with two pairs of parallel sides with equal length and two pairs of angles of equal measure. The area of the parallelogram (<em>A</em>), in square yards or square inches, equals the product of its base length (<em>b</em>), in yards, and its height (<em>h</em>), in yards.
The area of each parallelogram is determined afterwards:
<h3>Exercise 10</h3>
<em>A = (10.5 in) · (10 in)</em>
<em>A = 105 in² </em>
<h3>Exercise 11</h3>
<em>A = (9 yd) · (2.333 yd) </em>
<em>A = 20.997 yd²</em>
The areas of the two parallelograms are 105 square inches and 20.997 square yards, respectively.
