Answer:
lets start with the division
10/10
1
3+2 . 1 - 1
5 . 1 - 1
5. 1 = 5
5 - 1 = 4
Step-by-step explanation:
Answer:
true
Step-by-step explanation:
for example, when you solve an equation and you get something like 16=16, which is infinitely many solutions and is also a true statement
(a) 95 = (x+7)*(x-7)
(b) 95 = (x+7)*(x-7)
Expand the brackets:
95 = x² -7x + 7x -49 = x² - 49
Subtract x² from both sides:
95-x² = -49
Subtract 95 from both sides:
-x²=-49-95
-x²= -144
Divide both sides by -1 to get rid of the negative numbers:
-x²/-1=-144/-1
x²=144
Take the square root of 144:
x = ± squareroot of 144
x = 12 or -12
x = 12 because you cannot have a negative age so Trina is 12 years old.
Step-by-step explanation:
it will be answer B
2x^3+6x^2-4x-12
One liter is equal to 1000 milliliters. Use the conversion to find your answer. 1000 milliliters / 5mL per tube = 200 tubes
