Answer:
x^3(2x+1)(2x-1)
Step-by-step explanation:
first take common then use formula of a^2-b^2
Answer:
y=13
Step-by-step explanation:
Since we know that t = 3.4 you put 3.4 where the t is.
2 (36 - 4 × 3.4) So what you do first is multiply 4 and 3.4 which gives you 13.6
2 (36 - 13.6) then you subtract 36 and 13.6 which gives you 22.4
2 (22.4) then you multiply 2 and 22.4 which is 44.8.
So your answer is 44.8

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
Answer:
B. 271 square units
Step-by-step explanation:
The area is the sum of 3 rectangles areas
step 1 12 * 19 = 228
step 2 3 * 3 = 9
step 3 2 * 17 = 34
Now, we add all the answers we got to get the area.
= 228 + 34 + 9 = 271 square units
