Answer:
x^2+11x+30
Step-by-step explanation:
Answer:
Step-by-step explanation:
Yes it is a quadratic equation
5x^2 + 40x = -7
5x^2 + 40x + 7 = 0
a = 5
b = 40
c = 7
-40/10 <u>+</u> (sqrt(1600 - 4(5)(7)))/10
-4 <u>+</u> (sqrt(1600-160))/10
-4 <u>+</u> (sqrt(1440))/10
-4 <u>+</u> 12(sqrt(10))/10
-4 <u>+</u> 6/5(sqrt(10))
Answer:
b) 94
Step-by-step explanation:
The Total Degree of a Triangle is 180 degrees. Knowing this, set up an equation.
68+26+x=180.
x is the complementary angle of the "?" angle.
Solve the equation.
94+x=180
x=86
Then Subtract 86 from 180 to find "?"
180-86=94
I hope this helps!
