Answer:
The answer is -77
Step-by-step explanation:
Ok, so assuming by x2 you mean x squared, I will solve this. So basically when you have a function, f(-7) would mean that you would have to replace all the x's in the equation with -7. So let's write that out. that would be f(-7) = -7^2 + (-7*4). So now according to PEMDAS, you would solve the exponent first, and -7^2 is equal to -49, because when you solve it you would do -(7^2), which is -(49), which is then -49. So now you have f(-7)= -49+ (4*-7). Solving for (4*-7), you get -28. This leaves you with -49 + (-28), which is -49 - 28. Simplifying that, you get the answer, which is -77.
Answer:
35, 55, and 90 degrees
Step-by-step explanation:
The acute angles of a right triangle are complementary, so if the smallest angle measures x, the next largest angle measures (x+20) degrees. So, x+(x+20)=90, meaning x=35.
So, the angles measure 35, 55, and 90 degrees.
