Answer: 45 ft
Step-by-step explanation: 3 times 15 equals 45
Answer:
1.) x=4
2.) x=14
Step-by-step explanation:
FOR #1:
1.) In order to solve the parallelogram, you must know that each opposite sides must equal...
so KL=JM and KJ=LM
2.) To solve for "x", you must substitute

so it should end up with...

3.) Solve the equation with some algebra

FOR #2:
1.) In order for a square, rectangle, parallelogram, (or any shape with four sides), it must equal to 360°. And you just have two given angles, which equal to 180, so that means the unknown equals to 180...So in this case you should have

as your equation...
2.) Solve with algebra


<u><em>multiplied</em></u>
Answer:
a) 3 b) y = 3x + 11
Step-by-step explanation:
a)
In order to find the gradient (slope), find the change in y or change in x (rise/run).
-2 - 2 / 7 - (-5)
-2 - 2 / 7 + 5
-4/12 = -1/3
Now that we know the gradient of line AB is -1/3, take the opposite reciprocal of that to find the gradient perpendicular to line AB.
-1/3 ⇒ 3
b)
Take point C's values and the perpendicular gradient found earlier and substitute them into the point-slope form equation.
y - 5 = 3(x - (-2))
y - 5 = 3(x + 2)
y - 5 = 3x + 6
y = 3x + 11
Answer:
B. -5.
Step-by-step explanation:
fg(x) = (x - 1)(5x^2 + 19x - 3)
= 5x^3 + 14x^2 - 22x + 3
So fg(-4) = 5(-4)^3 + 14(-4)2 -22(-4) + 3
= -320 + 224 + 88 + 3
= -5.
