A picture has a height that is 2 times it’s width . It is to be enlarged to an area of 128 in 2
What will the dimensions of the enlargement be , if the equation to represent its area 2x 2 = 128
9514 1404 393
Answer:
8 in by 16 in
Step-by-step explanation:
In your equation, we presume that x represents the width. Solving for x, we have ...
2x² = 128 . . . . . . given equation
x² = 64 . . . . . . . . divide by 2
x = √64 = 8 . . . . square root
The enlargement will be 8 inches by 16 inches.

2 ( 2 ) = 4
5 ( 2 ) = 10
4/10 - 9/10
= -5/10
simplify
-5/10 = -1/2

100 points i just need helpp
Answer:
5sqrt(5) = q
-5sqrt(5) = q
Step-by-step explanation:
f(q) = q^2 -125
To find the roots set the equation equal to zero
0 = q^2 -125
Add 125 to each side
125 = q^2 -125+125
125 = q^2
Take the square root of each side
±sqrt(125) = sqrt(q^2)
±sqrt( 5*25) = q
±sqrt( 25)* sqrt(5) = q
±5* sqrt(5) = q
±5sqrt(5) = q

Mercedes can select from 2 types of apples and 3 types of pears. If she randomly selects 1 apple and 1 pear, how many possible choices does she have?
answer:
2,3
2,2
2,1
1,2
1,1
1,3
Those are the possible choices of selecting apples and pears.
If she randomly selects 1 apple and 1 pear then the possible choices are 6.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Given that, Mercedes can select from 2 types of apples and 3 types of pears.
Mercedes randomly selects 1 apple and 1 pear.
We need to find the number of possible choices does she have.
(2,3)(2,2)(2,1),(1,2)(1,1)(1,3)
The probability of choosing 1 apple from 2 apples will be 1/2.
The probability of choosing 1 pear from 3 pears will be 1/3.
Now the probability of choosing a apple and a pear will be
1/2×1/3
1/6
Hence, If she randomly selects 1 apple and 1 pear then the possible choices are 6.

why do we need to know the different abbreviation of measurements and its equivalent?
Answer:
See explanation.
Step-by-step explanation:
You will need to know the abbreviations of measurements because when pertaining to the real world, an you will see things as so "This fence is about 15ft tall." or "Jacobb is 72in tall." If you do not understand the abbreviations you will not understand what anyone is ever talking about when it comes to measurements. As for knowing how to convert measures to be equivalent, that is important because some measurements are bigger than others. It doesn't make since to say 12 inches, when you can just say 1 foot.
