I think X= 5^3
Hoped this helped!
Answer:
i think you did it right :)
Step-by-step explanation:
Notice that half of the coefficient of x is (1/2)(-4), or -2.
Then x^2 - 4x becomes
x^2 - 4x + 4 - 4 = 0, or (x -2)^2 = 4. Then x = -2 plus or minus 2, and the two roots are 0 and -4.
Thus, add 4 to both sides to obtain x^2 - 4x + 4 = 4.
Answer:
26 cm²
Step-by-step explanation:
the area of a triangle can be calculated using the following formula
1/2 bh
b=base
h=height
the base in this case is 6.5 cm
the height is 8 cm
so you multiply 8 and 6.5=52
then you divide 53 by 2=26
