Answer:
-4x^2 + 237x - 675
Step-by-step explanation:
(x - 3)*(232 - 4x -7) >> Distribute x and -3 to the trinomial
232x - 4x^2 - 7x - 696 + 12x + 21 >> Simplify
-4x^2 + 237x - 675
Answer:
4 divided by 5 is equal to 0.8. This decimal can also be written as a fraction. 0.8 = eight tenths or 8/10 (4/5 in its reduced form).
Step-by-step explanation:
Answer: <em>A. 241 feet</em>
Step-by-step explanation:
<em>The figure shows two rectangular triangles.
</em>
<em>These triangles are similar since they have two identical angles:
</em>
<em>the first angle is 90 degrees;
</em>
<em>the second angle is equal because the law of reflection states that the angle of incidence is equal to the angle of reflection.
</em>
<em>The law of reflection states that the angle of incidence is equal to the angle of REFLECTION.</em>
<em>Let's make the proportion:</em>

<em />
<em>It takes a minimum of 100 feet for a parachute to open and safely land without injury, so:</em>
<em>341.25 - 100 = 241.25 (feet)</em>
<em>241.25 ≈ 241 (feet)</em>
3/7 = 9/x
cross multiply because thats how u solve proportions
(3)(x) = (7)(9)
3x = 63
x = 63/3
x = 21
and if u will notice : 3/7 and 9/21 ....9/21 reduces to 3/7....so these are equivalent fractions...because proportions are nothing but equivalent fractions
