(2x² - 8x - 10) ÷ 2 = 0
x² - 4x - 5 = 0
x² + x - 5x - 5 = 0
x(x+1) - 5(x+1) = 0
(x+1)(x-5) = 0
x+1 = 0 or x-5 = 0
x = -1 or x= 5
S = {-1;5}

Answer:
8.84×10 To the power of -1
Step-by-step explanation:
stated number and decimal number is 8.84
goal: find the standard form of that number.
Defenition: (Plagarism Copyrights) The rules when writing a number in standard form is that first you write down a number between 1 and 10, then you write × 10(to the power of a number).
So 0.884 is 8.84/10
next put the numerator of 10 to 1 - 1/10
mulitiply 8.84 by 1/10-
this, the answer is multiply 8.84 by 10 to the power of -1
which is basically 8.84×10 To the power of -1

Step-by-step explanation:
Answer:
x = 8; y = 29
Step-by-step explanation:
In a parallelogram, opposite angles are congruent.
8x = 7x + 8
x = 8
4y = y + 87
3y = 87
y = 29
