Answer:
Let the side of one square be x. Area = x*x = x²
Then the side of other square would be 2x , Area = 2x*2x = 4x²
Combined area = x² + 4x² = 5x²
This combined area = 45 cm²
you simplify
Therefore 5x² = 45 Divide both sides by 5
x² = 45/5
x² = 9 Take square root of both sides
x = √9
x = 3
Length of larger square is 2x = 2*3 = 6 cm
Length of larger square = 6cm
Step-by-step explanation:
Answer:
x^2-4x+4-(x^2+6x+9)
Step-by-step explanation:
=x^2-4x+4-x^2-6x-9
=-10x - 5
Answer:
C
Step-by-step explanation:
Equation : -1x² - 14x + 2 = 0General Formula : b2-4ac=0a=-1, b= -14, c= 2Put the Value in General FormD = (-14)2 - 4 x -1 x 2D = 196--8D = 204
and the polynomial has 2 real roots
7/5 * 5/7y = 7/5 * 6
y = 42/5.
The multiplication property of equality is used.
Meredinth takes 24 minutes to reach her friend house
<em><u>Solution:</u></em>
Given that, Meredith lives 24 blocks from her friends house
She travels one block every minute
<em><u>To find: time taken by Meredith to reach friend house</u></em>
From given,
Number of blocks between Meredith house and her friedn house = 24
She travels one block every minute
Thus she takes 1 minute for 1 block
One block = 1 minute
So, for 24 blocks, we have to multiply by 24

Thus Meredinth takes 24 minutes to reach her friend house
