E(1,-4) F(1,-6) G(-3,-5) H(-3,-3)
They arent congruent when you look at the side lengths and area
Answer:
2(x - 7)(x + 2)
Step-by-step explanation:
Given
2x² - 10x - 28 ← factor out 2 from each term
= 2(x² - 5x - 14) ← factor the quadratic
Consider the factors of the constant term (- 14) which sum to give the coefficient of the x- term (- 5)
The factors are - 7 and + 2 , since
- 7 × 2 = - 14 and - 7 + 2 = - 5 , thus
x² - 5x - 14 = (x - 7)(x + 2) and
2x² - 10x - 28 = 2(x - 7)(x + 2)
Step-by-step explanation:
area of a circle= πr²
and r= half diameter
therefore we have r=10/2=5
area= 5² x π
area= 25π
circumference=2πr
circumference= 2xπx5
circumference=10π
