Answer:
x - intercepts are (-7,0) and (-2,0)
A is the correct option.
Step-by-step explanation:
We have been given the equation of the parabola 
For x- intercept, y = 0

We can split the middle term as 9x = 7x +2x

Now take GCF

Factored out the common term

Apply the zero product property

Solve for x

Hence, x - intercepts are (-7,0) and (-2,0)
A is the correct option.
Answer:
26.6 m
Step-by-step explanation:
Given the figures are similar
linear ratio = a : b
area ratio = a² : b²
here
area ratio = 16 : 25, then
linear ratio = 4 : 5 ( square root of both area ratio parts )
let the perimeter of the larger figure be x, then by proportion
=
( cross- multiply )
4x = 106.5 ( divide both sides by 4 )
x ≈ 26.6
Hence perimeter of larger figure is approximately 26.6 m
The answer would be -17.6.
Simplify 2.4 divided by 0.1 to 24 ( 6.4 - 24 )
Simplify ( -17.6 ).
