30m2 because the formula is base times height.I hope this helps
We know that
the x-intercepts of the quadratic function f(x)=x²<span>−3x−10 is when
f(x)=0
</span>x²−3x−10=0
Group terms that contain the same variable, and move the
constant to the opposite side of the equation
(x²−3x)=10
Complete the square. Remember to balance the equation
by adding the same constants to each side.
(x²−3x+2.25)=10+2.25
Rewrite as perfect squares
(x-1.5)²=12.25----------> (+/-)[x-1.5]=3.5
(+)[x-1.5]=3.5----> x1=5
(-)[x-1.5]=3.5-----> x2=-2
<span>
the answer is</span>
the x-intercepts of the quadratic function are<span>
x=5x=-2</span>
