Can someone solve these math problems?

1. An instructor predicted that grade test a student will be proportional to the amount of time the student spends studying. What is that? 4. If the length of a rectangle is doubled, only the area two measures? Why or why not? 5. If the height and the base of a triangle are doubled, what happens in the region? Explain your answer. 6. When is to solve an equation using the property also, how do you determine the number to add or subtract from both sides of the equation? (There are actually 10, but I have other down. I'm not sure at them, and I wanted to compare the answers. "0 points.

1. Suppose that X is the grade of the student and t is the time the student spends time as a student teacher, will be proportional to x, x / y = T or x = y * t where there can be any value —– positive, negative, decimal, integer. 4. area of a rectangle is given by Area, A = length * width. region is assumed, the length is L and B magnitude if the length is doubled, the area will be equal to A = 2L * B is clearly the double of the area with an original length of way area also doubles provided the scale remains the same. 5. area of the triangle is equal to A = (Base * height) / 2 if both base and height is twice the surface area increases by 4 times. 6. decide, by adding or subtracting this number, both sides this equation are gonna be equal.first begin by track number if u cannot decide .. then you will know if ur not close ch ..
