Answer: x=26

Step-by-step explanation:

1. Write the equation 2x-5+4x-1+30=180 because all triangle angles add up to 180°

2. Simplify the equation by combining like terms. Write the equation as 6x+24=180

3. Subtract 24 from both sides. Write the equation as 6x=156.

4. Divide 156/6 and get 26. That is your answer (x=26).

What two numbers have a difference of 5 and a product of 3.36

iris [78.8K]

X-y=5
xy=3.36
add y to both sides on first
x=5+y
sub that in other eqation
(5+y)y=3.36
expand
y^2+5y=3.36
minus 3.36 both sides
y^2+5y-3.36=0
use quadratic formula

for
ay^2+by+c=0
$y= \frac{-b+/- \sqrt{b^2-4ac} }{2a}$
for 1y^2+5y-3.36
$y= \frac{-5+/- \sqrt{5^2-4(1)(-3.36)} }{2(1)}$
$y= \frac{-5+/- \sqrt{25+13.44} }{2}$
$y= \frac{-5+/- \sqrt{38.44} }{2}$
$y= \frac{-5+/- 6.2}{2}$
y=-2.5+/-3.1
y=5.6 or 0.6
sub back

x=y+5
so
x=10.6 or 5.6

the numbers are either 10.6 and 5.6 or 0.6 and 5.6
wait,but 10.6 and 5.6 don't multiply to get 3.36 so that is an extrainiesous answer

answer is 0.6 and 5.6
