Answer:
(x + 2)(x + 5)
Step-by-step explanation:
For factored form you have to determine what two numbers multiplied by each other equal c that also, when added to each other, equal b.
Y= ax^2 + bx + c
a=1
b=7
c=10
the factors of 10 are 1, 2, 5, 10
and 2 + 5 = 7
and in factored form with a = 1
(x + 5)(x + 7)

Step-by-step explanation:
According phythagorous theorem,
x²=(12)²+(5)²
x²=144+25
x= root of 169
x=13
Answer:
3x
Step-by-step explanation:
Step-by-step explanation:
Number of sides of the given polygon, n =5
Sum of interior angles =( n-2)180°
=( 5 - 2)180°
= 3*180°
= 540°
Missing angle, x = 540°- (100°+105°+110°+145°)
= 540°- 460°
= 80°
