Answer:
A.
The angles may not be equal
only if the quadratic is inscribed in a circle and this quadratic is determined or said to be a cyclic quadrilateral then we may say that the angles are equal but here it may not.
Remember
a/b time b/a=1
find 1x
(7/8)x=-2/3
multiply both sides by 8/7 to clea fraction
1x=-16/21
Answer:
480 cm^3
Step-by-step explanation:
Total volume is the sum of the volumes of the 3 cuboids.
Cuboid at the bottom:
V = l×b×h
V = 12 × 5 × 4 = 240
Both on top are identical.
Their height is 10-4= 6 cm
Each has volume = 5×4×6 = 120
Total Volume = 240 + 120 + 120
= 480 cm^3
Answer:
4x - 12
Step-by-step explanation:
8-4(-x+5)
Distribute
8 - 4*-x -4 * 5
8 +4x - 20
Combine like terms
4x - 12
