This is Commutative property of addition
The coordinates would be multiplied by 3, as the scale factor is 3, and it is a dilation, so we know the size increases.
X^2+5^2=7^2
x^2+25=49
(49-25)
x^2=24
sqrt(24)=4.89897948557
Answer:
12 cups of mild
Step-by-step explanation:
3x3 is 9 and 3/4x9 is 12/4 so 3 9+3 is 12
Answer:
(7x-1)(x-3)
Step-by-step explanation:
7x^2 - 22x + 3
The factors have to add to -22, but multiply to equal 3. But since the "a" value has a number on it, you have to use it too.
(7x +/- [n1]) ( x +/- [n2]) = 7x^2 - 22x + 3
Since the two numbers multiply to a positive value, they have to have the same sign. (7x-1) (x-3) works to produce the expression when it's foiled.
