Perimeter..2times length plus 2 times width..
Answer: 108
Area..formula to find area of a parallelogram is base times height..
We don’t know the height
And since h is part of a dimension of a triangle..we can use this formula..a^2+b^2=c^2
225+b2=625
B^2=400
Square root of 400 is 20
So the height is 20
Hope it helped
Answer:
24x^2 - 66x + 15
Step-by-step explanation:
(2x-5)(4x-1) Use the FOIL or box method
8x^2 - 2x - 20x + 5 Combine like terms
8x^2 - 22x +5 Multiply by 3
3 (8x^2 - 22x +5)
24x^2 - 66x + 15

Answer:
(x + 5)(3x - 2)
Step-by-step explanation:
Assuming you require the expression factorised.
3x² + 13x - 10
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × - 10 = - 30 and sum = + 13
The factors are + 15 and - 2
Use these factors to split the x- term
3x² + 15x - 2x - 10 ( factor the first/second and third/fourth terms )
= 3x(x + 5) - 2(x + 5) ← factor out (x + 5) from each term
= (x + 5)(3x - 2) ← in factored form
