Answer:

x = 7

m < LMN = 130 degrees.

Step-by-step explanation:

13x - 31 = x + 53 (because these 2 angles are congruent).

13x - x = 53 + 31

12x = 84

x = 7.

and

m< LMN = 2 * m < MNO

= 2 * (7 + 53)

= 2 * 60

= 120 degrees.

Answer:

x=7 and m<LMN = 120

Step-by-step explanation:

if MO bisects LMN then 13x - 31 must be equal to x + 53

13x - x = 53 + 31

12x = 84

x = 7

and

13x - 31 + x + 53 = m<LMN

14x + 22 = m<LMN

since x is 7

14×7 + 22 = 120

Consider the equation below.

Korvikt [17]

Answer:

Equation in square form:

$y=3(x+5)^2-4$

Extreme value:

$(h,k)=(-5,-4)$

Step-by-step explanation:

We are given

$y=3x^2+30x+71$

we can complete square

$y=3(x^2+10x)+71$

we can use formula

$a^2+2ab+b^2=(a+b)^2$

$y=3(x^2+2\times x\times 5)+71$

now, we can add and subtract 5^2

$y=3(x^2+2\times x\times 5+5^2-5^2)+71$

$y=3(x^2+2\times x\times 5+5^2)-3\times 5^2+71$

$y=3(x+5)^2-75+71$

So, we get equation as

$y=3(x+5)^2-4$

Extreme values:

we know that this parabola

and vertex of parabola always at extreme values

so, we can compare it with

$y=a(x-h)^2+k$

where

vertex=(h,k)

now, we can compare and find h and k

$y=3(x+5)^2-4$

we get

h=-5

k=-4

so, extreme value of this equation is

$(h,k)=(-5,-4)$

Drag and drop the reasons for the steps into each box correctly to solve the equation

Viktor [21]

Yes your answers are correct :)

Step by step review:

First line has product of 5 and (x+2) so product property is good.

2nd line has division so quotient property is good.

3rd line has equal log with base 2 so equality property is good.

4th line has multiplication so that is also good

5th line has distribution of 5 and 7 so distributive property is good.

Your answer is correct.
