Answer:

solving the equation 5x^2 - 16 = 29 we get the solution: \mathbf{x=3,x=-3}

Step-by-step explanation:

We need to solve the equation 5x^2 - 16 = 29

We need to solve the equation to find the value of x.

We can solve this equation using simple DMAS rule.

We are given:

5x^2 - 16 = 29

Add 16 on both sides

5x^2 - 16+16 = 29+16\\5x^2=45

Now, divide both sides by 5

\frac{5x^2}{5}=\frac{45}{5} \\x^2=9

Now, we know that \sqrt{x^2}=\pm x

Taking square root on both sides.

\sqrt{x^2}=\sqrt{9}\\x=\pm3

So, we get values of x:

x=3, x=-3

Therefore, solving the equation 5x^2 - 16 = 29 we get the solution: \mathbf{x=3,x=-3}

Write two expressions to show a number increased by 11. Then, draw models to prove that both expressions represent the same thin
ioda

Answer:

n + 11 and 11 + n

Step-by-step explanation:

Let n be the unknown number,

n is increased by 11,

That is, n + 11

By the commutative property of addition,

The expression would be,

11 + n

For drawing a model that shows n + 11

Take two boxes in which first shows n and second shows 11 and add them,

Similarly, for showing 11 + n, take first box that shows 11 and second box that shows n then add them.

<t =33 since triangle  RUT is isosceles  (RU = TU)

<r + <u + <t = 180  triangle = 180

33 + <u + 33 = 180

66 + <u = 180

< u =114

<rus = < sut  from the diagram

<rus + <sut = <u

x + x = 114

2x = 114

divide by 2

x = 57

Q and R are independent events. P(Q) = 0.4; P(Q AND R) = 0.08. Find P(R).
algol [13]
Because Q and R are independent, you have

\mathbb P(Q\cap R)=\mathbb P(Q)\times\mathbb P(R)
0.08=0.4\times\mathbb P(R)
\implies \mathbb P(R)=0.2
