Answer:
<em><u>note:</u></em>
<em><u>find the attached solution</u></em>
Answer: 37.5
Explanation: find the surface area of one side, which is 2.5*2.5=6.25 then multiply that product by six, since there’s six sides in a square, and you’ll get 37.5
By <em>direct</em> substitution and simplification, the <em>trigonometric</em> function z = cos (2 · x + 3 · y) represents a solution of the <em>partial differential</em> equation
.
<h3>How to analyze a differential equation</h3>
<em>Differential</em> equations are expressions that involve derivatives. In this question we must prove that a given expression is a solution of a <em>differential</em> equation, that is, substituting the variables and see if the equivalence is conserved.
If we know that
and
, then we conclude that:

All angles add to 180 (interior angles)
22+53+?=180
75+?=180
minus 75 both sides
?=105
third angle is 105 degrees
Answer:
A
Step-by-step explanation:
The rhombus cuts the shorter side of the rectangle in half so it's equal to 5
we use pythagoras

so the larger side is 2x=24
so the area is 24*10=140cm^2
