V<span>ertical angles are equal.
We have 4x = 2x + 18.
Then, 2x = 18;
x = 18 </span>÷ 2;
x = 9 degrees;
The measure of angle DBE is 2 × 9 + 18 = 36 degrees.
Answer:
Step-by-step explanation:
Expression; coefficient, variable; constant; substitute, though I think it should be substitute 7 for x, not 3 for x; and simplify
Answer:
<em>B. (U+V)(U-V)</em>
Step-by-step explanation:
<u>Factoring</u>
The given expression is:
It should be noted that both terms are perfect squares:
Since it's a difference of squares, we need to use the following pattern to factor the required expression:
Thus, the answer is
B. (U+V)(U-V)
Step-by-step explanation:
<em><u>Given</u></em><em><u>, </u></em>
r ÷ 6 = 10
=> r = 10 × 6
=><em><u> r = 60 (Ans)</u></em>
<h3><em><u>Checking</u></em><em><u>. </u></em><em><u> </u></em><em><u>:</u></em></h3>
LHS = r ÷ 6. <em><u>RHS</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em>10
<em>[</em><em>By</em><em> </em><em>putting</em><em> </em><em>value</em><em> </em><em>r</em><em> </em><em>=</em><em> </em><em>60</em><em> </em><em>]</em>
= 60 ÷ 6
= 10
<u><em>Hence</em><em>,</em></u>
<u>Hence,<em>LHS</em><em> </em><em>=</em><em> </em><em>RHS</em><em> </em></u><em><u>verified</u></em><em><u>. </u></em>
I’m kinda confused but I’d go with:
Expand the brackets
-2xA = 82
/-2 on both sides
xA = -41
/x on both sides
A = -41/x
