Answer:
(A) 21
Step-by-step explanation:
5x-15 needs to equal 90 since it is a right angle and 21 makes that true

Answer: 2(n + 4) (n - 4)
Step-by-step explanation:
Since both terms are perfect squares, factor using the difference of squares formula,
a^2 - b^2 = ( a + b ) ( a + b )
True because it has 4 equal sides and 4 equal interior angles each measuring 90 degrees
Answer:
23
Step-by-step explanation:
3 * [2 + (12 - 2 * 4)] + 5
~Multiply whats in parenthesis
3 * [2 + (12 - 8)] + 5
~Subtract whats in parenthesis
3 * [2 + (4)] + 5
~Add whats in brackets
3 * 6 + 5
~Multiply
18 + 5
~Add
23
Best of Luck!
Hey there!
Three points to keep in mind!
- The given options are in standard form: ax+by=c
- The line is a solid line, hence, the possible outcomes would be ≤ or ≥
- The shaded part is above the line, hence, the symbol would be ≥
First, let's find the slope:
Slope : (y2-y1)/(x2-x1)
Slope : (0-3)/(2-0)
Slope : -3/2
Looking at line, we know that the y-intercept is 3 b=3
Slope intercept form:
<em>y≥(-3/2)x+3 </em>
Let's now convert this into a standard form:
<em>(3/2)x+y≥3 </em>
<em>Multiplying all the sides with 2: </em>
<em>Remember that the coefficient of 'x' shall not be negative or a fraction!</em>
<em>3x+2y≥6 </em><em>is the final answer!</em>
