Answer:

g = 5

Step-by-step explanation:

Solve for g:

4 (g - 1) + 2 (g + 5) = 36

4 (g - 1) = 4 g - 4:

4 g - 4 + 2 (g + 5) = 36

2 (g + 5) = 2 g + 10:

2 g + 10 + 4 g - 4 = 36

Grouping like terms, 4 g + 2 g - 4 + 10 = (4 g + 2 g) + (-4 + 10):

(4 g + 2 g) + (-4 + 10) = 36

4 g + 2 g = 6 g:

6 g + (-4 + 10) = 36

10 - 4 = 6:

6 g + 6 = 36

Subtract 6 from both sides:

6 g + (6 - 6) = 36 - 6

6 - 6 = 0:

6 g = 36 - 6

36 - 6 = 30:

6 g = 30

Divide both sides of 6 g = 30 by 6:

(6 g)/6 = 30/6

6/6 = 1:

g = 30/6

The gcd of 30 and 6 is 6, so 30/6 = (6×5)/(6×1) = 6/6×5 = 5:

Answer:

g = 5

Step-by-step explanation:

given

4(g - 1) + 2(g + 5) = 36 ← distribute left side and simplify

4g - 4 + 2g + 10 = 36

6g + 6 = 36 ( subtract 6 from both sides )

6g = 30 ( divide both sides by 6 )

g = 5

Find the area of the triangle.

Vsevolod [243]

Answer:

20 m²

Step-by-step explanation:

Formula (Area of triangle):

$\text{A (Triangle)} = \dfrac{1}{2} \times \text{Base} \times \text{Height}$

From the triangle, we can see that the base of the triangle is "7 + 3" m and the height of the triangle is "4" m.

$\implies \text{A (Triangle)} = \dfrac{1}{2} \times (7 + 3) \times (4)$

Simplify the right-hand-side as needed to evaluate the area.

$\implies \text{A (Triangle)} = \dfrac{1}{2} \times (10) \times (4)$

$\implies \text{A (Triangle)} = \dfrac{40}{2} = 20 \ \text{m}^{2}$

Therefore, the area of the provided triangle is 20 m².

Hitung jarak di antara titik P(7, 1) dengan titik Q(7, 8)

MaRussiya [10]

Answer:

7 units

Step-by-step explanation:

Distance between 2 points

= $\sqrt{(y1 - y2)^{2} + (x1 - x2) {}^{2} }$

Thus, distance PQ

$=\sqrt{(8 - 1)^{2} + (7 - 7)^{2} } \\ = \sqrt{7^{2} } \\ = 7$

Or you could simply take 8-1= 7 since both points have the same x-coordinate. Thus, PQ is a vertical line and the distance between them is due to the difference in their y-coordinate.
