It's B. An isosceles triangle has two angles that are the same because they are across from 2 sides that are the same. Therefore, these 2 angles must have the same measure. Because of the triangle angle-sum theorem, all the angles add up to 180. So 180-90 = 90 and 90/2 = 45
Product is multiplication.
The opposite of 4 is -4
3 x -4 = -12
Answer: -12
Answer:
x = -3
y = 8
Step-by-step explanation:
x + 2y = 13 ------------(I)
x = 13 - 2y -----------(II)
-2x - 3y = -18 ----------(III)
Substitute x = 13 - 2y in equation (III)
-2*(13 - 2y) - 3y = -18
-2*13 - 2y *(-2) -3y = -18
-26 + 4y - 3y = -18 {Combine like terms}
-26 + y = -18 {Add 26 to both sides}
y = -18 + 26
y = 8
Substitute y = 8 in equation (II)
x = 13 - 2*8
= 13 - 16
x = -3
x = -3
y = 8
1584 yards cubed.
Convert all the measurements to inches.
9*12=108
11*12=132
Multiply 108 and 132 to get the area.
108*132=14256
Multiply 14256 by 4 to get the volume.
14256*4=57024
Divide by 36, because there are 36 inches in a yard.
57024/36= 1584 Yards Cubed
