4 0

Answer: 8:9

Step-by-step explanation: Two find this answer, you need to see what will be the greatest number they can divide by (greatest common divider), it needs to be the same number for both 18 and 16. What number can go into both numbers, and is the greatest number? The answer is two, now you divide 2 by 18 and 16, so you'll get 8:9.

Hope this helps have a BLESSED and wonderful day! :-)

What values of x make the equation x2 + 9x – 22 = 0 true? Check all that apply. –11 –2 0 2 11
Marat540 [252]
Answer:  x = 2 ;  -11 .
___________________________________
Explanation:
_____________________________________________
Given the equation:
_____________________________________________
  x² + 9x −<span> 22 = 0  ;  Solve for:  "x" ;
_____________________________________________

Let us factor the "left-hand side" of the equation:
_____________________________________________
  "x</span>² + 9x −<span> 22"  ;
_____________________________________________

What are the factors of "-22"" that add up to "positive 9" ?
_____________________________________________
  Let us list the factors of "-22" :
____________________________________________
-2, 11;  </span>→ -2 + 11 = 9 ;<span>
-11, 2;  </span>→ -11 + 2 = -9 ;<span>
____________________________________________

So we have:  "-2" and "11" ;
____________________________________________
So;   </span>  "x² + 9x − 22" ; factors into " (x−2)(x + 11)" ;
____________________________________________
We have:  (x−2)(x + 11) = 0 ;

So:  x − 2 = 0 ;  

Add "2" to each side of the equation; 

     x − 2 + 2 = 0 + 2 ; 

          x = 2 ; 
___________________________________
   x + 11 = 0 ;

Subtract "11" from each side of the equation;

   x + 11 − 11 = 0 − 11 ;

      x = -11 ; 
___________________________________
 Answer:  x = 2 ; -11 .

SA= ( BH + 2LS +LB)

B= 16
H=6
L=8
S=10

SA= ( 16*6 +2(8*10) +8*16)=
SA= (96+2(80)+128)=
SA= (96+160+128)=
SA= 384

A cube had a volume of 1/512 cubic meter. What is the length of each side of the cube using the formula "volume=Length×Width×Hig
MrRa [10]

Answer:

The length of each side of the cube is \frac{1}{8}\ m

Step-by-step explanation:

we know that

The volume of a cube is equal to

V=LWH

but remember that in a cube

Length, width and height have the same value

so

Let

b-----> the length side of the cube

L=W=H=b

substitute in the formula

V=(b)(b)(b)=b^{3}

In this problem we have

V=\frac{1}{512}\ m^{3}

substitute and solve for b

b^{3}=\frac{1}{512}

b=\sqrt[3]{\frac{1}{512}}\\ \\b=\frac{1}{8}\ m

therefore

The length of each side of the cube is \frac{1}{8}\ m
