Answer:
sure. x=12
Step-by-step explanation:
firstly! we know that the two sections equal 90 degrees (because a right angle is 90 degrees). so, take both of those sections, and put them equal to 90 in an equation.
it would look like this...
(x+42) + (3x) = 90
which is the same as...
<u>x + 42</u> + <u>3x</u> = 90. ignore the parenthesis. they're just for clarification. then we will solve for x!
add similar things together! see x and 3x? those are similar because they have x in them. (HOWEVER! if it's something like x² and x, do not add them together!) x is the same as 1x, by the way. so 1x + 3x. ignore the Xs and add the numbers. it becomes 4x
4x + 42 = 90
move 42 to the other side by minusing it on both parts of the equation!
4x = 90 - 42
4x = 48
divide 48 by 4 so x is alone. there ya go
Answer:
6
Step-by-step explanation:
(g × f)(x) = g(x) × f(x) = x²(- x + 5)
To evaluate (g × f)(- 1) substitute x = - 1 into the product
x²(- x + 5)
= (- 1)²(- (- 1) + 5)
= 1(1 + 5)
= 1 × 6 = 6
