Answer:
x=21
Step-by-step explanation:
69+90= 159
180-159=21
X2<span> - 25 = x</span>2<span> - 5</span>2<span> = (x - 5)(x + 5)

The coordinates of the vertices of the triangle are
(–8, 8), (–8, –4), and<span> (10, –4)</span>.
Consider QR the base of the triangle. The measure of the base is b = 18 units, and the measure of the height is h = <span>12</span> units.
The area of triangle PQR is<span>108</span> square units.
the answer a is 6 and b is 2
The first term a1 is given to be -4. The formula for the next terms: an = an-1 + 7 means to add 7 to the previous term to get the next.
-4, 3, 10, 17, 24, 31
Answer A
