Out of numbers: 5, 7, 21, 25, 28, 35, 42, 56, 75, and 80, choose those which are multiples of 4 or 7
Anestetic [448]
Answer:
Multiples of 4= 28
Multiples of 7= 7,21,28,35,42
Step-by-step explanation:
I hope this helps, and have a great day! :)
3 + 5x = 20 + 7x
First subtract 20 to both sides
-17 + 5x = 7x
Next subtract 5x to both sides (we are trying to get x all in one side)
-17 = 2x
Divide 2 to isolate the x
-17/2 = x or -8.5 = x

we are given that , a ladder is placed against a side of building , which forms a right angled triangle . We wre given one side of a right angled triangle ( hypotenuse ) as 23 feet and the angle of elevation as 76 ° . We can find the Perpendicular distance from the top of the ladder go to the ground by using the trigonometric identity:

Here,
- hypotenuse = 23 feet
= 76°- Value of Sin
= 0.97 - Perpendicular = ?

The first x coordinate is given by 0 and the second one is given as j. So the length of the base is j. (Sometimes in math they give letters rather than numbers. And since you know it is an isosceles then the other vertex should be at x-coordinate half j or j/2.
Answer:
0
Step-by-step explanation:
Substitute the given values for a and b into the expression
(18 + 14) - (18 - 14)²
=
× 32 - 4²
= 16 - 16
= 0
