Answer:
A false B true c false
Step-by-step explanation:
3 (-3^2 × 1^5) + 4 (-3 - 8)^2
3 (9 × 1) = 27 + 4 (121) = 484
27 + 484 = 511
Answer:
6- 8- 10 triangle with 10 as the hypotenuse
Step-by-step explanation:
In any right triangle the hypotenuse must be the longest side.
This is only true for the 6- 8- 10 with 10 as the hypotenuse.
Also using Pythagoras' identity
6² + 8² = 10²
When calculating A×B, the number of columns of A = number of rows of B.
Thus, only last case is possible.
Answer:
30
Step-by-step explanation:
20+2((3)(7)−(4)(4))
=20+2(21−(4)(4))
=20+2(21−16)
=20+(2)(5)
=20+10
=30
