Answer=36inches tall
Explanation= 44+10= 54
90-54=36in
4x²+4x-35=0
factor: (2x+7)(2x-5)=0
2x+7=0, or 2x-5=0
2x=-7 or 2x=5
x=-3.5 or x=2.5
I don't see any rounding necessary in this case.
when you factor ax²+bx+c, you take the two factors of a and the two factors of c, one factor of a times one factor of c, the other factor of a times the other factors, the sum of the two products make b.
in this case, the factors of 4 is 2 and 2, the factors of -35 is -5 and 7. I line them up in the following way:
2 -5
2 7
then I multiple them diagonally, the top left 2 multiplying the bottom right 7=14, and the other 2 multiplying -5=-10, 14 and -10 make a sum of 4.
if you don't get the desired sum, switch the factors up and down till you have the right combination. Note: Do not switch left and right.
I hope this makes sense to you.
Answer:
Assuming the slide is straight - 12 feet
Step-by-step explanation:
Assuming the slide is straight - it creates a right triangle with long side 13 feet and one of the short sides of 5 feet. We need to find the other short side.
We know that:
The answer is 1,2,3,6,7,14,21,42
Answer:
42 plants
Step-by-step explanation:
Dimensions are missing.
Suppose a right triangle has a base of length 7yards and a height of 24 yards.
As you know, Area of triangle can be determined by
Area of triangle 'A'= 1/2 x b x h = 1/2 x 7 x 24
A= 84 yards²
Now she wants 2 plants for each square yard of area
therefore, if the area is 84 yards²:
number of plants are 84/2=> 42 plants
Thus, She wants 42 plants in the garden
