Answer:
y= (x+4)(x+4) is the answer
Step-by-step explanation:
Identity used= (a+b)²= a²+2ab+b²
Answer:
k=45
Step-by-step explanation:
Since the sum of the measures are 180 and the measures are 45 degrees, k degrees, and 2k degrees, we can conclude that 
. 2k and k are like terms, so you can add 2k and k to get 3k.Then, you would have 
. Since you are finding k, you want to isolate k as best you can. To do this, you subtract 45 on both sides 
as shown by the equation, 180-45 is 135. Then, you divide 3 on both sides to get k=45.
Answer:
25.5in²
Step-by-step explanation:
A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs
Characteristics of a trapezoid
It has 4 vertices and edges
If both pairs of its opposite sides of a trapezoid are parallel, it becomes a parallelogram
Area of a trapezoid = (1/2) x (sum of the lengths of the parallel sides) x height
1/2 x (6 + 11) x 3 = 25.5 in²
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
X is great her than or equal to 7
Answer:
Altura = 20,000 cm
Step-by-step explanation:
V = (pi x r^2 x a)/3
1.696.464 = (3.14 x 9^2 x a) / 3
1.696.464 = 84,82 altura
1.696.464 / 84,82 = altura
a = 20,000cm
