Angle A + Angle B = 180 degrees
180 = (6x -48) + (4x +38)
180 = 10x -10
190 = 10x
x = 19
Angle A = 6x - 48
Angle A = 6 * 19 - 48
Angle A = 115 -48
Angle A = 67 degrees
Angle B = 4x + 38
Angle B = 4*19 + 38
Angle B = 76 + 38
Angle B = 114
2x2 − 12x + 21. Axis of symmetry. 2.
The answer is Y=63/128X+961/128
Answer:
x= 0.5
or x= -1.5
Step-by-step explanation:
Let's solve your equation step-by-step.
4x2+4x−3=0
Step 1: Factor left side of equation.
(2x−1)(2x+3)=0
Step 2: Set factors equal to 0.
2x−1=0 or 2x+3=0
x= 1/2 or x= −3/2
Answer: a) 9 cm
explanation: since the length of the rectangle is 4 cm greater than the width, you can just take 9 cm (the length) minus 4, which gets you 5 cm. if we use the area formula (length x width), then 9 x 5 = 45 square cm.
