Answer:
(x-4)² = 44
Step-by-step explanation:
To complete the square, take the middle term -8x and divide the coefficient in 2 and square it. Here it is -8/2 = -4. -4² = 16. Add 16 to both sides.
x² - 8x - 10 = 18
x² - 8x + 16 - 10 = 18 + 16
(x-4)² - 10 = 34
(x-4)² = 44
Answer:
Step-by-step explanation:
The second expression 5 (x minus 3) the third 4 x + 3 y minus 15 minus 3 y + x
and there is no more
Answer:
B. 15 + 5√3.
Step-by-step explanation:
The ratio of the sides in a 30-60-90 triangle is 1:√3:2.
So here the lengths of the sides are 5, 5√3 and 10.
Perimeter = 15 + 5√3.
Answer:
4/5 fractions aren't my strong suit but should be eight hopefully
