Answer:
I think its, Find the value of x such that PQ = QR, where P , Q, and R are the points (2, 5 ),( x, -3 ), and ( 7, 9 ), respectively.
Step-by-step explanation:
Answer:
115 in²
Step-by-step explanation:
SA = Area of triangular surfaces + area of the square base
SA= 2bh + b²
SA = 2(5)(9)+5²
SA = 90+25
SA = 115
Answer:
3(2x + 3y)
Step-by-step explanation:
Here, we want to divide
The inner term of the first part can be splitted by the use of the difference of two squares
That is;
given two perfect squares, separated by negative; we can write the factors as;
a^2-b^2 = (a-b)(a + b)
Thus;
4x^2 - 9y^2 = (2x-3y)(2x + 3y)
matching term for term;
6x/2x will give 3
while (2x-3y)(2x + 3y)/(2x-3y) = 2x + 3y
So we have the results of the division as;
3(2x + 3y)
Step-by-step explanation:
the (A) formula is preferable to use and is the correct one
Try to find the lowest common denominator. In this case it's 28, which makes our numbers as follows:
1/4 = 7/28
1/7 = 4/28
7/28 + 4/28 = 11/28
We can't simplify it so that's the result.
