Show steps to solve 2-16.5=4-7.5​

Mathematics
1 answer:
ASHA 777 [7]3 years ago
7 0

Answer:

11=0

or

-11=0

keep in mind that you get these answers by completely simplifying the equation, but they are both false

Step-by-step explanation:

step 1: simplify both sides

2-16.5 simplifies to -14.5

4-7.5 simplifies to -3.5

so you get -3.5 = -14.5

step 2: add one side to the other to get a zero on one side

add 3.5 on both sides to get 0=-11

or

add 14.5 on both sides to get 11=0

step 3: evaluate the statement

since both -11 and 11 are not equal to 0, this statement is false

Complete the square to factor X^2 +10X=-8
ella [17]

Answer: x=\sqrt{17}-5 and x = -\sqrt{17}-5

Step-by-step explanation:

Alright, lets get started.

The given equation is :

x^{2} +10x = -8

Adding 8 in both sides, it will become

x^{2} +10x + 8 = -8 +8

x^{2} +10x + 8 = 0

To make it perfect square, we need to add 25 and subtract 25

x^{2} +10x + 8 +25-25= 0

x^2+10x+25+8-25=0

(x+5)^2+8-25=0

(x+5)^2-17=0

Adding 17 in both sides  

(x+5)^2=17  

taking square root

x+5=\sqrt{17}

So,

x=\sqrt{17}-5 and x = -\sqrt{17}-5  .. Answer

Hope it will help :)

GH bisects FGI. Find the measure of HGI<br><br> •15°<br> •21°<br> •10°<br> •8°
tester [92]

Answer:

m<HGI=21°

Step-by-step explanation:

we know that

If GH bisects m<FGI then

m<FGH=m<HGI

substitute the values

(2x+1)°=(3x-9)°

solve for x

3x-2x=1+9

x=10°

The measure of angle HGI is equal to

(3x-9)° ------> substitute the value of x

3*10-9=21°

m<HGI=21°
