Answer:
x = 1
Step-by-step explanation:
So, let the unknown number be x
then 3x + 4 = 7
3x = 7 - 4
3x = 3
x = 3/3
x = 1

You don't really know where the x is. The way you have written it, technically its like this. (-3^2)*x and none of the answers agree with that.
It must be -3^(2x) + 5 In that case 0,4 works. That gives (-3)^0 = -1
-1 + 5 = 4
Unfortunately so does 1,-4 because -3^2 = - 9
- 9 + 5 = - 4
If (-2,76) is the answer, then the question should be written (-3)^(2x) - 5
Until the ambiguity is gone, we're not sure.
Answer:
1e+15
Step-by-step explanation:
Answer: She is not correct, because she must multiply the base and the height of the triangle and then divide by 2.
Step-by-step explanation:
1. The formula for calculate the area of a triangle is shown below:

Where
is the base and
is the height.
2. Then, if she applied the method she reasoned, she'd obtain the following area:
3. But actually, Magda should multiply the base and the height of the triangle and then divide by 2. Then, the correct area is:
