Answer:

7 units is the answer

Step-by-step explanation:

points are (-9,-8) and (-2,-8)

Pythagorean theorem can written as,

$d=\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2} \\\\d=\sqrt{(-2-(-9))^2 + (-8-(-8))^2}\\\\d=\sqrt{(7\\)^2+(0)^2} \\\\d=\sqrt{49} \\\\d=7 \\\\$

∴ d = 7 units

Rahul solved the equation 2(x – ) – 2 left-parenthesis x minus StartFraction 1 Over 8 EndFraction right-parenthesis minus StartF

VladimirAG [237]

Answer:

Step 3

Step-by-step explanation:

The solution is given in the image attached. The steps are:

Step 1:

$2x-\frac{1}{4} -\frac{3}{5}x=\frac{55}{4}$

Step 2: simplifying the coefficients of x:

$2x -\frac{3}{5}x-\frac{1}{4}=\frac{55}{4}\\\frac{10x-3}{5} -\frac{1}{4}=\frac{55}{4}\\\frac{7x}{5} -\frac{1}{4}=\frac{55}{4}$

Step 3: Adding 1/4 to both sides

$\frac{7x}{5} -\frac{1}{4}+\frac{1}{4} =\frac{55}{4}+\frac{1}{4}\\ \frac{7x}{5}=\frac{55+1}{4}\\ \frac{7x}{5}=\frac{56}{4}\\$

Step 4: Multiplying both sides by 5/7

$\frac{7x}{5}*\frac{5}{7} =\frac{56}{4}*\frac{5}{7} \\x=10$

The addition property of equality states that if a number is added to both sides of an equation, the equation is still valid (i.e the equation is still the same). From the steps above, The addition property of equality was applied in step 3

Un trapèze a une aire de 39 cm2. Sa grande base

V125BC [204]

Answer:

A = bh/2

39 = b*3/2

39*2 = b*3/2 * 2

78 = b*3

78/3 = b*3/3

26 = b.

Alors, la grande base est 26 cm et le petit base serait 26/3 = 8.67 cm arrondi.
