38 divided by 40, then multiply by 100 = 95%
Hello,
2x - one over four of (12x + 4) = 3
must be written:
2x-1/4 *(12x+4)=3
And we see a sign '-' before 1/4.
Step 1:
2x-(3x+1)=3 or 2x-3x-1=3 and not 2x+3x-1=3
Answer A
since Step 1, because incorrect signs have been used
And here, Mehek are there sufficients explanations?
Answer:
The correct option is:
h = 1, k = 16
Step-by-step explanation:
y=4x^2-8x+20 =0
It is a quadratic formula in standard form:
ax^2+bx+c
where a = 4 , b = -8 and c=20
The vertex form is:
a(x − h)2 + k = 0
h is the axis of symmetry and (h,k) is the vertex.
Calculate h according to the following formula:
h = -b/2a
h= -(-8)/2(4)
h = 8/8
h = 1
Substitute k for y and insert the value of h for x in the standard form:
ax^2+bx+c
k = 4(1)^2+(-8)(1)+20
k = 4-8+20
k=-4+20
k = 16
Thus the correct option is h=1, k=16....
Answer: 6 units
Step-by-step explanation:
I know that in a triangle, there's two angles that have equal measures, then the sides opposite to them are equal in length. Thus, the length of side AB is 6 units.
