1) The correct answer would be -48/-6.
-48 divided by -6 equals to 8.
48 divided by -6 equals to -8.
Because a positive (8) is always bigger than a negative (-8). The second option is correct.
_____________
2) The correct answer is -6.
5 * 2 = 10.
And 4 - 10 = (-6)
Isolate the variable by dividing each side by factors that don't contain the variable.
x > -9
(a) 3(x+2)=180-35-52
3x+6=93
3x=93-6
3x=87
x=87÷3
x=29
The Value Of x Is 29.
(b) x=29
angle C=3(x+2)
=3x+6
=3(29)+6
=87+6
=93
The Measure Of Angle C Is 93.

Answer:
3) ? = 21
4) ? = 6
Step-by-step explanation:
3) The given ratio is ...
A : B = 2 : 7
You want to find ? such that ...
2 : 7 = 6 : ?
The ratio is equivalent when both numbers are multiplied by the same value.
From your knowledge of multiplication tables, you know that 2×3 = 6. then 7×3 = ? = 21.
__
4) For this one, you need to recognize that the given number corresponds to B.
A : B = 2 : 3
2 : 3 = ? : 9
Again, you know that 3×3 = 9, so 3×2 = ? = 6.
Answer:
Step-by-step explanation:
A rectangular prism (or orthohedron) is a polyhedron whose surface is formed by two equal and parallel rectangles called bases and by four lateral faces that are also parallel rectangles and equal two to two.
The orthohedron is a straight prism and also a particular case of irregular quadrangular prism.
In a rectangular prism you can differentiate the following elements:
Bases: are two parallel and equal rectangles.
Faces: the four rectangles of the lateral faces and the two bases. Therefore, it has six faces.
Height : distance between the two bases of the prism. The height h coincides with any of the edges of the lateral faces.
Vertices: the eight points where three faces of the prism converge.
Edges: segments where two faces of the prism are found.
The surface area of the rectangular prism (or orthohedron) is calculated by the following formula:
where w is width, l is length, and h is height.
Solving with l = 15mm, w = 3mm, and h = 4mm
