Step-by-step explanation:
This will result to 3k+4=22 because minus times minus is plus
Therefore, 3k=22-4, when +4 crosses over the equals to sign it becomes -4
=> 3k=18
=> Divide both sides by 3 to get k
=> k=6
Answer:
the shape of the box is a rectangular prism.The way to solve this is by using the formula V=l*w*h
we only have 20(l) and 10(h) so here's a clue it said that the base of the box was squared so the width would also be 10 in. so....
V=20*10*10
₃
=2000 in
Step-by-step explanation:
Answer:
x = 10
Step-by-step explanation:
smaller triangle / bigger triangle = 20 / 28
hence,
3x / (4x+2) = 20/28
28(3x) = 20(4x+2)
84x = 80x + 40
4x = 40
x = 10
Answer:
f(1·2)
Step-by-step explanation:
Subbing x=1 (f(1)) into the original function f(x)=a^x will give f(1)=a^1 which is simply equal to a. Therefore, if we were to do [f(1)]^2, we would just get a^2 because f(1) is equivalent to a. Out of the choice.s present, only f(1·2) is equal to a^2, because a^(1·2)=a^2
