If the domain of the square root function f(x) is x<7, which statement must be true? O7is subtracted from the x-term inside the radical.
O The radical is multiplied by a negatve number.
O7is added to the radical term.
O The x-term inside the radical has a negative coefficient.

1; 35 is the ratio

step-by-step explanation:

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1

step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45
