Answer:
x = - 104, y = - 130
Step-by-step explanation:
the quotient of the 2 numbers is
=
( cross- multiply )
5(x + 26) = 4x
5x + 130 = 4x ( subtract 4x from both sides )
x + 130 = 0 ( subtract 130 from both sides )
x = - 130
First number is - 130 + 26 = - 104
second number is - 130
Answer:
Options (1), (2) and (4)
Step-by-step explanation:
1). Since, pyramid given in the picture is a rectangular pyramid,
Area of the rectangular base = Length × Width
= 6 × 4
= 24 cm²
2). There are four lateral sides of the pyramid.
3). Lateral sides of the pyramid are not congruent.
4). Total surface area = Area of the lateral sides + Area of the rectangular base.
Area of one lateral side =
=
= 9.2 cm²
Area of second lateral side =
= 12 cm²
Area of the lateral sides = 2(9.2) + 2(12)
= 42.4 cm²
Total surface area = 42.4 + 24
= 66.4 cm²
5). Area of the one face =
= 12 cm²
Area of the second face =
= 9.2 cm²
Therefore, Options (1), (2) and (4) are the correct options.
