Answer:
27 ft
Step-by-step explanation:
Im assuming you need to find the area of the triangle based on the information you are given...
In that case, plug the values into the formula for tirangle area:
To get:
Solve to get: 27
12: 1.57c
13: $70.65
14: $25.65
2.5 rounded is 3, and 2.549 rounded is 2.5
They are both correct.
Answer:
When x = 64, y = 80.
Step-by-step explanation:
Since the origanal value was 8 and now it´s 64, lets divide to see how much was multiplied. Then lets multipliy it with that number.
64 / 8 = 8
Soo..8 x 10 = 80.
When x = 64, y = 80.
Let's solve your equation step-by-step.

</span>Step 1: Subtract 5 from both sides.
<span><span><span><span>−<span>x^2</span></span>−<span>2x</span></span>−5</span>=<span>5−5
</span></span><span><span><span><span>−<span>x^2</span></span>−<span>2x</span></span>−5</span>=0
</span>Step 2: Use quadratic formula with a=-1, b=-2, c=-5.
