one number is 4 less than 3 times another number. If their sum is increased by five,the result is 25. Find both the numbers.
Answers
Answer:
6 and 14
Step-by-step explanation:
let the second number=x
the first number=3x-4
(x+3x-4)+5=25
4x-4+5=25
4x+1=25
4x=25-1
4x=24
x=6
Since x is the first number,the first number is 6
second number=3•6-4
=18-4=14

the area of square is 64cm square .find its length
Answers
Answer:
8 cm
Step-by-step explanation:
Because A=a*a
Area equals length times length
So, 8 is the length
64 divided by some number must equal the exact same number. Let me show what I am talking about.
Our length is a. We multiply a times itself (because that's the formula for the square's area)
Does this number exist?
Yes, it does.
And it's a whole number.
And we know from our times tables that 8*8=64

Answer:
528 cm squared
Step-by-step explanation:
A parallelogram (slanted shape at the bottom) is essentially the same area as a rectangle.
Therefore, both shapes have the same measurements.
Multiply the length and height of the rectangle to get its area: 22cm×12cm =264cm squared
Since the area of the rectangle corresponds geometrically to the area of the parallelogram, just multiply the area of the rectangle (264cm squared), by 2.
So 264×2, = 528cm squared
