What does -2/3 (x + 5) + 4 (x + 5) - 10/3 (x + 5) equal

Kitty [74]

Answer: 0

Step-by-step explanation:

$-\frac{2}{3}(x+5)+4(x+5)-\frac{10}{3}(x+5) = ?$

$-\frac{2}{3}x-\frac{10}{3}x+4x+20-\frac{10}{3}x-\frac{50}{3} = ?$

$(-\frac{2}{3}x+4x -\frac{10}{3}x) +(-\frac{10}{3}+20-\frac{50}{3})=?$

$(-\frac{12}{3}x+4x)+(-\frac{60}{3}+20)=?\\ (-4x+4x)+(-20+20)=?\\0+0=0$

Please help with this area question. I have gotten my answer but I am not too sure about it, and want to make sure my reasoning

Pie

Answer:

Step-by-step explanation:

Area of triangle= ½ ×base ×height

Since the length of the base and the height of the triangle is equivalent to the length of a side of the square, s,

area of triangle

= ½ ×s ×s

= ½s²

Given that the area of the triangle is 12.5 units²,

½s²= 12.5

Multiply both sides by 2:

s²= 12.5(2)

s²= 25

Square root both sides:

$s = \sqrt{25}$

s= 5 units

(reject negative value since s > 0)

What is the value of x?<br> O x = 32<br> O x = 36<br> O x = 37<br> O x = 40

kozerog [31]

Answer:

x=40

Step-by-step explanation:

I went through each answer one by one and the only one that satisfies the question is 40.

The line equals 180°, so x + (4x-20) must equal 180.

x+(4x-20)

40+(4(40)-20)

40+(160-20)

40+140=180

x=40
