Answer:
No solution or
(-3±
)/8
Step-by-step explanation:
To get the solution, move everything to the left side of the equation:
8x²+6x+5 = 0
If you try to factor the equation or graph it, you will see that it will never equal 0.
If you need an imaginary solution you can plug it into the quadratic equation:
-6±
over 16
Simplify and you get
-6±
over 16
-6±
over 16
Simplify the fraction and you can get
(-3±)/8
First subtract y from both sides to isolate the variable.
25 = 2y-2
Next, add 2 to both sides.
27 = 2y
Last, divide by 2.
13.5 = y
Answer:
The answer is b. 72.3cm
Step-by-step explanation:
11.5cm is the radius
To find the circumference multiply the radius by 2 then multiply it again by 3.14
3.14 is the beginning of pi.
e.g - 2 × 3.14 x 11.5
<span>In a triangle the sum of two sides is always greater than the third side.
12-5 < x < 12+5
7 < x < 17 </span>← answer
a is SSS, c is SAS and d is ASA, all good congruent triangle theorems.
b is AAA, good to show similar triangles, not necessarily congruent triangles.
Answer: b
