Answer:
-308
Step-by-step explanation:
Given that:
=(−2.2 )·(−2)·(−14)·(5)
- As "-" sign into "-" becomes "+"
- (2.2)(2) = 4.4
=(4.4)*(-14).(5)
=(4.4)*(-70)
= -308
I hope it will help you.
3x+7y=-6 -7x+3y=26 -4x+4y=-32 +4x on both sides and you end up with 4y=-32+4x now divide both sides by 4 and you get y=-8+x then to incorporate that in one of the problems 3x+7(-8+x)=-6 do the distributive property with the 7 into the () and you get 3x-56+7x=-6 now add all common variables and get 10x-56=-6 now add 56 to both sides and you get 10x=50 now divide by 10 on both side and you get x=5 now for getting y to equal a number instead of an equation 3(5)+7y=-6 15+7y=-6 subtract 15 on both sides to get 7y=-21 not divide by 7 on both sides to get y=-3 your answers are y=-3 and x=5

Answer:
<h2>
16.6 ft</h2>
Step-by-step explanation:
The height of the house, the ground and the ladder forms a right angle triangle, with the following parameters stated below.
1. the hypotenuse is the length of the ladder which is 30 feet
2.the opposite is the height of the house, which is 25 feet
3. the adjacent is the distance of the ladder away from the building, this is the parameter we are solving for.
Since we have two sides of the triangle given, we can employ Pythagoras theorem to solve for the third side of the triangle
let the the opposite be x
we know that

Solving for x we have

Hence the maximum distance away from house that he can place
the ladder is 16.6 ft to the nearest foot
