Answer:
2(2x + 5)(2x - 5)
Step-by-step explanation:
2(2x + 5)(2x - 5)
= (4x + 10)(2x - 5)
= 8x² - 20x + 20x - 50
= 8x² - 50
Answer:
Step-by-step explanation:
x1 = 0.5 x2 = -0.4 y1 = 1.3 y2 = -1.3


=2.75
To solve for x just isolate x by moving the other variables so....:
First add c to both sides
g+c= y+x
Subtract y from both sides
g+c-y= x
That should be your final answer (we cannot come up with an actual digit for x because there are no numbers in this equation we simply can make an equation for x)
Hello! I am happy to help you.
Here, x=36.
2*36=72*2=144+36=180. A triangle's measure equals 180.
Hope this helps!
