The sum of two numbers is 369 the difference of those two numbers is 17 which answer choice shows both numbers

SVETLANKA909090 [29]

Answer:

(176, 193)

Step-by-step explanation:

Well you forgot to put in the choices, but:

The difference between the numbers is 17. Let's call the smaller number x and the bigger one y

(x + y) = 369

y = x + 17

(x + (x + 17)) = 369

2x + 17 = 369

2x = 352

x = 176

y = x + 17 = 193

the area of a rectangle is 30 to the square root of 3750 square inches, and the length is 3 to the square root of 250 inches. wh

uranmaximum [27]

<h3>Answer:</h3>

$\sf { width =10 \sqrt{15} \:inches}$

<h3>Solution:</h3>

We are given that:

Area of rectangle is 30√3570
Length of the rectangle is 3√250

Area of rectangle is given by:

$\implies\quad{\pmb{ \sf{Area = length\times width}} }$

Hence, putting the values in the formula:

$\implies\quad \sf{ A = l\times w}$

$\implies\quad \sf{ 30\sqrt{3750}=3\sqrt{250}\times w}$

$\implies\quad \sf{3\sqrt{250}\times w = 30\sqrt{3750} }$

$\implies\quad \sf{ w =\dfrac{30\sqrt{3750}}{3\sqrt{250}}}$

$\implies\quad \sf{ w =10\dfrac{\sqrt{3750}}{\sqrt{250}}}$

$\implies\quad \sf{ w = 10\times\sqrt{\dfrac{3750}{250}}}$

$\implies\quad \underline{\underline{\pmb{\sf{ w =10\sqrt{15}}}}}$
