Answer:
x = ±6
Step-by-step explanation:
x^2/4=9
Multiply by 4 on each side
x^2/4 *4=9*4
x^2 = 36
Take the square root of each side
sqrt(x^2) = ±sqrt(36)
x = ±6
Answer:
9/4
Step-by-step explanation:
The divide symbol is also the line that separates the numerator and the denominator, so 45÷20 can also be written as 45/20.
We can see that both 45 and 20 are divisible by 5, so we can simplify the fraction down to 9x5/4x5, and then we cancel out the 5s and are left with 9/4
Answer: the answer is -2 1/3
Step-by-step explanation: it would be -2 1/3 because 5 + 2=7 and then add the 1/3 to make -7 1/3
Answer:
25%
Step-by-step explanation:
let length of 1st square be x and second be y
then
A/q
x = y/2
area of first square = x^2 = (y/2)^2 = (y^2)/4
and
area of second square = y^ 2
so from sbove two lines
area of first square = 1/4 * area of second square
= 1/4 *100%
so..
area of first sqare = 25% of area of second square
