Answer:
C. 49 sq units
Step-by-step explanation:
Area of a triangle is
A = 1/2bh
base is 14 and height is 7
14 * 1/2 is 7
7*7 = 49
Since the whole figure including all the points is enlarged at the same time, the dilated figure will still have the same slope and that includes the fact that point T is still in line Y'Z'. The slope or shape does not change, only the size alters.The center of dilation is still at Point T in this case.
Let's do this in steps, show your work! | <em>Make sure to ask questions!</em>
#1. Simplify 5x - 4 + 3 to 8x - 4.
<u>8x - 4 = 36.</u>
#2. Add 4 to both sides.
<u>8x = 36 + 4. </u>
#3. Simplify 36 + 4 to 40.
<u>8x = 40.</u>
#4. Divide both sides by 8.
<u>x = 40/8.</u> <------ <em>It turned into a fraction because it's easier to not divide a decimal. </em>
#5. Simplify 40/8 to 5.
<u>x = 5. </u>
<h3>Therefore, x = 5.</h3>
