I don’t know how to solve this
V125BC [204]

Assuming that both triangles are an exact copy of one another, it is safe to assume that 3y-7 is equal to 41. Set up an equation

3y-7=41

Add 7 to both sides

3y=48

Divide both sides by 3

y=16


Now to find PN.

Based on what we know, we can assume that MP = PN. Let's make some equations!

MP = 17x-8     PN = 11x+4

17x-8 = 11x+4

Subtract 11x from both sides

6x-8 = 4

Add 8 to both sides

6x = 12

Divide by 2

x=2

Substitute 2 in for x in the equation for PN

11(2)+4

Multiply 11 by 2

22+4 = 26

PN = 26

Madeline was completing the square and her work is shown below. Identify the line where she made her mistake.. . f(x) = 3x^2 + 6
MAVERICK [17]
In completing the square, the first step is to factor out the first and second term so that the factor (x+a) is highlighted. This is seen in line 1. However, in line 2, the subtracted value should be 3 so as to compensate for the added value. This affects then line 3 as well. The answer is line 2.

Evaluate (−23)×(−23)3 by using the Laws of Exponents
Nikolay [14]

Given:

\left(-\dfrac{2}{3}\right)\times \left(-\dfrac{2}{3}\right)^3

To find:

The value of given expression by using the Laws of Exponents.

Solution:

We have,

\left(-\dfrac{2}{3}\right)\times \left(-\dfrac{2}{3}\right)^3

Using the Laws of Exponents, we get

=\left(-\dfrac{2}{3}\right)^{1+3}      [\because a^ma^n=a^{m+n}]

=\left(\dfrac{-2}{3}\right)^{4}

=\dfrac{(-2)^4}{(3)^4}      [\because \left(\dfrac{a}{b}\right)^n=\dfrac{a^n}{b^n}]

=\dfrac{(-2)\times (-2)\times (-2)\times (-2)}{(3)\times (3)\times (3)\times (3)}

=\dfrac{16}{81}

Therefore, the value of given expression is \dfrac{16}{81}.
