Find attached the first sum.
x denotes horizontal and y denotes vertical
When the value of x is positive, it moves to right side and when x is negative, it moves left sides 'x unit'
When the value of y is positive, it moves to up side and when y is negative, it moves down sides 'y unit'
which statements are true when solving x*2 -8x +16=0?
A x=+4.
B Factor to solve.
C x=4 is a double root.
D Complete the square root to solve.
E The equation is a perfect trinomial.
Given:
The given equation is
[tex]x^2-8x+16=0[/tex]
To find:
The correct statement for the given equation.
Solution:
We have,
[tex]x^2-8x+16=0[/tex]
It can be written as
[tex]x^2-2(x)(4)+(4)^2=0[/tex]
Using the identity of perfect square trinomial, we get
[tex](x-4)^2=0[/tex] [tex][\because (a-b)^2=a^2-2ab+b^2][/tex]
[tex](x-4)=0[/tex]
[tex]x=4[/tex]
Here, x=4 has multiplicity two because the power of factor (x-4) is 2.
x=4 is a double root and the equation is a perfect trinomial.
Therefore, the correct options are C and E.
Answer:
B) Factor to solve.
C) x = 4 is a double root.
E) The equation is a perfect square trinomial.
Step-by-step explanation:
Factor to solve.<
By inspection, the equation is a perfect square trinomial.
x = 4 is a double root
By inspection, the middle term's coefficient 8 is twice the square root of 16, the constant; therefore, it is a perfect square trinomial.
x2 − 8x + 16 = 0 → (x − 4)(x − 4) = 0 → x = 4 is a double root.

Answer:
x=24
Step-by-step explanation:
I think that its just a degree sign tbh
but because pc is a radius and so is pd their opposite angles are equal to each other.
so angle d and angle c are congruent
then because a triangles angles add up to equal 180 we do
180=x+54+x+54+x and solve for x
step 1 combine like terms x+x+x=3x 54+54=108
180=3x+108
step 2 subtract each side by 108
3x=72
step 3 divide each side by 3
x=24
hope this helps (:
Answer:
x = 36
Step-by-step explanation:
BD is a diameter.
<BCD is an inscribed angle whose sides intersect the endpoints of a diameter. Therefore m<BCD = 90.
m<BCD = x + 54 = 90
x + 54 = 90
x = 36

Bags of sugar come in 3 sizes:
Small bag: A 250 g bag costs 60p.
Medium bag: A 500 g bag costs £1.30.
Large bag: A 3 kg bag costs £7.50.
Calculate the cost of 3 kg for the small and medium bags.
Give your answer in pounds to 2 dp.
Write the bag that is the better value in the comments.
Answer:
Small bag: £7.20 for 3 kg
Medium bag: £7.80 for 3 kg
Best value: small bag
Step-by-step explanation:
3 kg = 3000 g
Small bag: 60p/250 g = 0.24p/g
For 3000 g: 0.24p/g * 3000 g = £7.20
Medium bag: £1.30/500 g = 0.0026 £/g
For 3000 g: 0.0026 £/g * 3000 g = £7.80
Large bag:
For 3000 g: £7.50
Best value: small bag
