Answer:
Step-by-step explanation:
(x-4) (x+10) ⇒ (x+a)(x+b)=x²+(a+b)x+ab
a=-4 , b=10
x²+(-4+10)x+-4(10)
x²+6x-40
(3x+4) (3x +5)
3(x+4/3) *3(x+5/3) ⇒ identity : (x+a)(x+b)=x²+(a+b)x+ab
a=4/3 b=5/3
3*3=9
9[x²+(4/3 +5/3)x+4/3(5/3)]
9[x²+9/3 x+20/9]
9x²+27x+20
(-3a +5b +4c)^2 ⇒
suitable identity is (a+b+c)²= a² + b² + c² + 2ab + 2bc + 2ca
a=-3a , b=5b , c=4c
9a²+25b²+16c²- 30ab +40bc - 24ca
Answer:
13,1cm
Step-by-step explanation:
1 : 13
1 : 170,18cm
170,18cm divided 13 : 170,18cm
13,090cm : 170,18cm
or
13,1cm : 170,18cm
bobble head is
13,1cm
cmiiw!
Answer:
the answer is study (thank me later)
Step-by-step explanation:
Answer:
(- 3, - 13 ) and (8, 1 )
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Both equations are in vertex form
(8)
y = 5(x + 3)² - 13
with vertex = (h, k) = (- 3, - 13 )
(9)
y = (x - 8)² + 1
with vertex = (h, k) = (8, 1 )
