The value of x is √8/3 - 2
Step by step explanation:
The given equation is
3(x+2)^2=8
To find x,
(x+2)²= 8/3
By taking square root on both sides
x+2= √8/3
x=√8/3 -2
x= -0.37
Thus the square root for the given value is -0.37
Answer: 37%
Step-by-step explanation:
Answer: 9
Step-by-step explanation: Here, we have the expression <em>4x - 7</em> and we want to evaluate the expression when <em>x</em> is equal to 4.
To evaluate an expression, we simply plug the value
of the variable into the expression and solve.
So here, since <em>x</em> is equal to 4, we have 4(4) - 7.
4(4) is equal to 16.
So we have 16 - 7 which is equal to 9.
So the value of our expression when <em>x</em> is equal to 4 is 9.
Answer:
-3a^2= -3*(-6)^2
Step-by-step explanation:
-3a^2 = -3*a^2 = -3*(-6)^2
Answer:
Step-by-step explanation:
You need to set up a ratio for the original recipe and then use that ratio for the new one.
If we need 3 cups of flour for every 4 cups of sugar, we have a 3 c flour/4 c sugar ratio, or 3/4
The new ratio is 9 c of flour for ? c of sugar. Those ratios have to be the same, so we set up an equation like this:
3/4 = 9/?
In order to keep the same ratio, you have to multiply by the same number. Since 3*3 = 9, multiply 4*3 to get your answer.
