Answer:
(2) 6x^2+40x +50
Step-by-step explanation:
(4x+10)*(2x+5) = 8x^2 +40+50
minus 2x^2
=6x^2 +40 +50
Answer:
m∠E = 60°
Step-by-step explanation:
The given information in the diagram are;
The shape of the drawing, ΔEDF = A right triangle
The length of the hypotenuse side opposite the right angle = 16·√46
The length of the leg adjacent to the reference angle ∠E = 8·√46
By trigonometric ratio, we have;
Plugging in the values gives;
∴ m∠E = arccos(1/2)
Using a calculator or from tables or an online trigonometric ratio tool, we have
arccos(1/2) = 60°
∴ m∠E = arccos(1/2) = 60°.
Answer:
(x^3 +8)/(x+2) = x^2 -2x +4
Step-by-step explanation:
Answer:
1560 square yards
Step-by-step explanation:
The area of the trapezoid is the base times the average of the 2 heights.
That is equal to 40*(36+42)/2=1560 :)
