Answer:
21
Step-by-step explanation:
We know that the sqaure root of 121 = 11.
So, A - 10 = 11
=> A = 21
 
        
                    
             
        
        
        
X^3 -9x+1= 0 (minus 1) 
X^3-9x=-1 (divide by 9)
x^3-x=-1/9 
But it doesn’t work any further so you have written it wrong 
        
             
        
        
        
Answer:
<h3>Attachment</h3>
Step-by-step explanation:
Convert to the slope-intercept form (<em>y = mx + b</em>):
 <em>divide both sides by 2</em>
             <em>divide both sides by 2</em>

We choose any three x values and calculate the y value:
for x = -1

for x = 1

for x = -3

Mark the points on the coordinate plane and draw a line through the given points.

Let:
 Strawberry
 Strawberry
 Grape
 Grape
The given parameter can be represented as:

Required
The question is incomplete as what is required is not stated.
Possible questions could be to determine the number of strawberries given a certain number of grapes, and vice versa
Take for instance
Calculate the number of grapes when there are 20 strawberries
We have:

This becomes

Express as fraction

Make G the subject



<em>i.e. 50 grapes</em>
<em>Apply the same method given a certain number of grapes</em>
 
        
             
        
        
        
We know that V = a^3 and that it's 1000 cubic meters (or unit cubes as long as one unit cube is 1x1x1m). We can write the calculation as attached below. The result (dimensions of one cube house) is
 10x10x10 meters.
