The diagonals of this rhombus are 8 and 16 units long. Their intersection creates four right angles, two 4-unit-long segments, a

Roman55 [17]

Answer:

$64\ \text{sq. units}$

Step-by-step explanation:

Area of a rhombus is the product of the length of the diagonals divided by two.

Length of one diagonal is 8 units and the other diagonal is 16 units

Area is given by

$A=\dfrac{8\times 16}{2}\\\Rightarrow A=64\ \text{sq. units}$

The area of the rhombus is $64\ \text{sq. units}$

Another approach is the diagonals have created 4 triangles where the base and is height is either 4 units long or 8 units long so the area of the rhombus would be the area of the 4 triangles.

$A=4\times \dfrac{1}{2}\times 4\times 8\\\Rightarrow A=64\ \text{sq. units}$

What is the solution of the following equation? 2x-5+3x=35

harina [27]

<em>2x - 5 + 3x = 35 </em>

<em>simplify </em>

<em>5x - 5 = 35 </em>

<em>add 5 to both sides </em>

<em>5x - 5 + 5 = 35 + 5 </em>

<em>simplify </em>

<em>5x = 40 </em>

<em>divide both sides by 5 </em>

<em>5x/5 = 40/5 </em>

<em>simplify </em>

<em>x = 8 </em>

State the domain of the rational function. f(x) = seventeen divided by quantity five minus x

alexandr1967 [171]

If we are going to write the equation in its mathematical form, we will see that it becomes,

<span> f(x) = 17/(x – 5)</span>

The domain of the function is the number of x that would allow us to solve the equation and get a real value for f(x). In this equation, x can take any real numbers so long as it is not 5. This is because 5 – 5 in the denominator will lead to 0 which in turn makes the equation indefinite.

What number solves the equation x + 7.4 =11.2

Sunny_sXe [5.5K]

The value of x is 3.8

<em><u>Solution:</u></em>

<em><u>Given equation is:</u></em>

$x + 7.4 = 11.2$

We have to solve the equation for "x"

Move the terms so that you end up with only terms involving x on one side of the sign and all the numbers on the other

Therefore, we get

x + 7.4 = 11.2

When we move 7.4 from left side to right side of equation it becomes -7.4

x = 11.2 - 7.4

Subtract 7.4 from 11.2

x = 3.8

Thus value of x is 3.8
