Su = 15 !!!!!!!!!!!!!! chile i hope Im not wrong lol
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>
Answer:
f) 5x 3
Step-by-step explanation:
You do multiplication first
Answer:
All of your choices are correct.
Step-by-step explanation:
4.50 ÷ 18 = .25 each
.25 x 4 = 1.00
.25 x 36 = 9.00
12 x .25 = 3.00
Answer:
length= 17.5
width=11.5
( I worked this out myself but I don't know if its right tho)
