X² <span>− 3x − 70=0
</span>x² + 7x - 10x − 70=0
x(x+7) - 10(x+7) = 0
(x+7)(x-10) = 0
x + 7 = 0 or x - 10 = 0
x = -7 x = 10
Answer: x=-7, x=10
3 times 219 is 657 so you need 6 hundred value blocks 5 ten value blocks and 7 one value blocks
Answer:
5
Step-by-step explanation:
You do 12 x 3 which is 36.
you then do 1/3 x 3 which is 1.
36-1 is 35.
you then do 4x3 which is 12.
you then do 12-5 which is 7.
you then do 35÷7=5
this is why it is 5.
You move the were the decimal to the 2 places to the right and its 3.4%
