Answer:
-4
Step-by-step explanation:
Since the total score <em>I</em><em>n</em><em>c</em><em>r</em><em>e</em><em>a</em><em>s</em><em>e</em><em>d</em><em> </em>by eight than the two matching cards must have been -4.
(total of four cards) + (two matching cards) = total score
(total of four cards) + (two cards × -4) = total score
(total of four cards) - 8 = total score
* take away two matching cards by adding 8 on both sides*
(total of four cards) = total score + 8
Answer:
B. 5x^4+5x^3
Step-by-step explanation:
(f.g)(x) = f(x) * g(x) = 5x^3 * (x+1)
= 5x^3 * x + 5x^3 * 1
= 5x^4 + 5x^3
Answer:
Step-by-step explanation:
Circumference C=2pi*r
But in question C=40pi
This implies that 2pi*r=40pi
This implies that r=20 in.
d=2*r=40 in.
Hope this helps :)
Answer:
<h3>When an ice cube tray, filled with water is placed in a freezer, it slowly loses heat and start to cool down to become ice cubes. Changing of water into an ice cube is an exothermic reaction. Snow formation in clouds is also an exothermic reaction. Clouds come into existence from condensation of water vapor.</h3>
