Answer:
13.7 cm²
Step-by-step explanation:
area of yellow region = area of square - area of 4 quarter circles
area of square = 8² = 64
area of 4 congruent quarter circles = area of circle
area of circle with radius = 4
A = π × 4² = 16π
yellow region = 64 - 16π ≈ 13.7 cm²
Answer:
2(4x + 1)(x + 1)
Step-by-step explanation:
Given
8x² + 10x + 2 ← factor out 2 from each term
= 2(4x² + 5x + 1)
To factor the quadratic
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 4 × 1 = 4 and sum = + 5
The factors are + 1 and + 4
Use these factors to split the x - term
4x² + x + 4x + 1 ( factor the first/second and third/fourth terms )
= x(4x + 1) + 1 (4x + 1) ← factor out (4x + 1)
= (4x + 1)(x + 1), thus
4x² + 5x + 1 = (4x + 1)(x + 1) and
8x² + 10x + 2 = 2(4x + 1)(x + 1) ← in factored form
Answer:
not solvable
Step-by-step explanation:
so there is a ratio of 5:3
that equals 8 parts
if you divide 60 by 8 that's 7.5
times 7.5 by 5 and you get 37.5
don't know how u get half a person but that's just how it is
Answer:
x=1
Step-by-step explanation:
14+2x+7=9x
2x-9x=7-14
-7x= -7
x= -7/-7
x=1
