A+c = 150
10.25a+7.75c = 1470
Answer:
Step-by-step explanation:
In order to factor out the Greatest Common Factor of polynomials, we first have to find the factors of the given polynomials. There are various methods to do that. Now we will write the steps needed to factor out the Greatest Common Factor of polynomials:
a) Breaking down every term into prime factor form.
b) Then we have to look for factors that appear in every single term in order to get Greatest Common Factor of polynomials
c) Now the Greatest Common Factor is taken out or factored out from every term before parentheses and group the remaining expression inside the parentheses.
Answer:
Width = 6.45 cm
Length = 8.6 cm
Step-by-step explanation:
the sides of a rectangle are such that the width is three-quarters of the length. if the diagonal is 15cm find the length and the width.
From the question,
W = 3/4L
W = 3L/4
When given diagonal,
W² + L² = D²
Where, D = Diagonal
W = Width
L = Length
Hence, Substituting 3L/4 for W
(3L/4)² + L² = 15²
9L²/16 + L² = 225
L²(9/16 + 1) = 225
Divide both side by 9/16 + 1
L² = 225/(9/16 + 1)
Square root both side
L = √225/(9/16 + 1)
L = 15/3/4 + 1
L = 15 ÷ 1 3/4
L = 15 ÷ 7/4
L = 15 × 4/7
L = 8.6cm
W = 3L/4
W = 3(8.6)/4
W = 6.45cm
