Answer:
Step-by-step explanation:
To find this equation in standard form, first, write it in factored form. This looks like . Then, multiply the polynomials using the FOIL (First, Outside, Inside, Last) method.
- Following the FOIL method, you should multiply the first terms in each binomial, , which equals .
- Then, the outside terms, . This equals .
- Next, the inside terms, .
- Finally, the last terms, , this equals .
Then, add all of the terms together . To get the standard form, combine like terms, this comes out to .
Answer:
x= -2
Step-by-step explanation:
If the slope is zero, that means the line is horizontal.
Answer:
40.3 in²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = h (a + b)
where h is the height and a, b the parallel bases
Here h = 6.2, a = 8, b = 5, thus
A = × 6.2 × (8 + 5) = 3.1 × 13 = 40.3 in²
Step-by-step explanation:
on applying ,
(a+b)²=a²+2ab+b²
So, c = 25 or (5)²
