Answer:
lhs = (5+2√3)/(7+4√3)
= [(5+2√3)(7-4√3)]/[(7-4√3)(7+4√3)]
=[35-20√3+14√3-24]/[7²-(4√3)²]
=[11-6√3]/[49-48]
=11-6√3
therefore
11-6√3 = a+b√3
compare both sides
a= 11, b= -6
Step-by-step explanation:
Hope this answer helps you :)

Answer:
a = 11, b = 6
Step-by-step explanation:
Given
Rationalise the denominator by multiplying numerator/ denominator by the conjugate of the denominator.
The conjugate of 7 + 4 is 7 - 4
= ← expand numerator/ denominator using FOIL
=
=
= 11 - 6
with a = 11 and b = 6

Answer:
G'(-4, -3)
G'(3, 4)
G'(-8, 6)
Step-by-step explanation:
Coordinates of the original point G on the graph → (-4, 3)
When the point G is reflected over the x-axis,
Rule to be followed fro the reflection,
(x, y) → (x, -y)
By this rule image of the point G will be,
G(-4, 3) → G'(-4, -3)
Rule for the rotation by 90° clockwise,
(x, y) → (y, -x)
G(-4, 3) → G'(3, 4)
Rule for the translation of 4 units left and 3 units up,
(x, y) → [(x - 4), (y + 3)]
G(-4, 3) → [(-4 - 4), (3 + 3)]
→ (-8, 6)
Answer: -5
Explanation: The number in front of your variable is called your coefficient.
A variable is just a letter that represents any number.
So in this problem, the -5 is the coefficient since
it appears in front of the the variable x.
