Answer:
36 cm²
Step-by-step explanation:
Area of a parallelogram = base x height
So area of parallelogram ABCD = BC x AM
To calculate the length of AM, use Pythagoras' Theorem a² + b² = c²
(where a and b are the legs and c is the hypotenuse of a right-angled triangle).
So using this theorem: BM² + AM² = AB²
⇒ 3² + AM² = 5²
⇒ AM² = 16
⇒ AM = √16 = 4 cm
(positive solution only as length cannot be negative)
Therefore, area of parallelogram ABCD = (3 + 6) x 4 = 9 x 4 = 36 cm²
Answer:
-2x^2 - 5x
= -2-4^2 - 5*-4
= -2(-4 * -4 ) - (-20)
= -2(-16) +20
= -32 + 20
= -12
Step-by-step explanation:
this is the quadratic formula
The volume of the prism is 15.625 because 2.5×2.5= 6.25 and 6.25 ×2.5= 15.625. Can I please get brainliest?
<span>Since these are done in order, and without replacement:
Lila selecting black = 7/12 (7 black ribbons out of 12 ribbons total)
Jessica *then* selecting a green ribbon = 5/11 ( 5 green ribbons left out of 11 ribbons left)
Chance of this specific event = (7/12)*(5/11) = 35/132</span>Mike <span>· 6 years ago</span>
