You would add like terms so it would be 1x then you add 1 to 7 so you would get 8.. the you divide both sides by 1x and you'd get 8=x
Answer:
6 feet
Step-by-step explanation:
This problem involves using ratios to compare side lengths in similar triangles.
136/34=x/1.5
136/34*1.5=x/1.5*1.5
136/34*1.5=x
x=6
The man is 6 feet tall
Area of a rectangle is length x width.
Let the width = x
The length would be x +7. ( 7 inches longer than the width)
Area = 20
Set up the formula:
20 = x * x+7
Simplify the right side:
20 = x^2 + 7x
Subtract 29 from both sides:
X^2 + 7x -20 = 0
Solve using the quadratic equation
X = -b + sqrt(b^2 -4ac) / 2a
X = -7 + sqrt(7^2-4(1)(-20) / 2(1) (exact answer)
X = 2.178908 ( as a decimal)
The width is 2.178907 inches (round as needed)
The length would be 9.178907 inches ( round as needed.)
Depending on how you round, when you multiply them together you get approximately 20 square inches.
Answer:
if two parallel lines are cut by a transversal, then alternate interior angles are <em>congruent</em><em> </em>
Answer:
B
Step-by-step explanation:
The Pythagorean Theorem only applies to right triangles.
The formula is:
, where a and b are the legs of the triangle and c is the hypotenuse.
Given any right triangle, the above formula holds true. Thus, the answer is B.
