Explain why 3(5x) does not equal to (3 times 5)(3times x)

Mathematics
1 answer:
Anit [1.1K]4 years ago
7 0

Answer:

Because 3(5x) is the same as 3 *5 * x

Step-by-step explanation:

When a number is next to another in parantheses, it signifies multiplication. In this case, we already have 5 and x grouped together by a multiplication sign, so the entire thing is 5 * x. The statement below is key

Distribution in multiplication is only possible if a variable is grouped to another real number by a plus or minus sign.

So in this case, we have 3 * 5 * x, which is 15x. However, if we had 3(5 + x), we would have 15 (3 * 5) + 3x (3 * x).

Hopefully that makes sense!

Triangle FGH, with vertices F(2,-8), G(7,-7), and H(6,-4), is drawn inside a rectangle, as shown below.
Semmy [17]

The area of the triangle FGH is 13√10 unit²

Given,

The vertices;

F(2, -8), G(7, -7), H(6, -4)

We have to find the area of the triangle.

Area of triangle = 1/2bh²

Here,

Area of triangle FGH = 1/2 (GH) (FG)²

Now,

Length of FG = \sqrt{(7-2)^{2} =(-8--7)^{2} }  = \sqrt{5^{2}+1^{2}  }  = \sqrt{25+1} = √26

Length of GH = \sqrt{(-7--4)^{2}+(7-6)^{2}  } = \sqrt{-3^{2}-1^{2}  } = \sqrt{9+1} = √10

Then,

Area of triangle FGH = 1/2 (GH) (FG)²

Area of triangle FGH = 1/2 × √10 × √26²

Area of triangle FGH = 1/2 × √10 × 26

Area of triangle FGH = 13√10

Therefore,

The area of the triangle FGH is 13√10 unit²
