Answer:
see below
Step-by-step explanation:
0 = x^2 + 6x – 10
Add 10 to each side
10 = x^2-6x
Take the coefficient of x
-6
Divide by 2
-6/2 =-3
Square it
(-3)^2 =9
Add 9 to each side
10+9 = x^2-6x+9
We use -3 for the square term
19 = (x-3)^2
Take the square root of each side
±sqrt(19) = x-3
Add 3 to each side
3±sqrt(19) = x
Answer:
<h2>x = 52.5 cm</h2><h2 />
Step-by-step explanation:
this is called a ratio and proportion or similar triangles
<u> 21 </u> = <u> 35 </u>
31.5 x
do cross multiply:
21 x = 31.5 (35)
x = 1102.5 / 21
x = 52.5 cm
