To find the area, you must split the kite into many triangles.
(5*7*0.5)*2 + (4*5*0.5)*2 = 55
Answer: 55 square meters
Answer : B
The dot where the y- axis is 2 and x-axis is 0 would be your y-intercept . For the other 2 dots with planes (3,8) and (2,6) you would do rise over run and connect them. Go down 2 and left 1 so they meet and divide. Once you divide 2 by 1 you get 2 so your equation would be y=2x+2 a.k.a B
Answer: B
Answer:
The answer is b) 2(2x-4) and c)
Step-by-step explanation:
Okay lets try a) 2(2x-6)
2 x 2x - 2 x 6= 4x-12
b) 2(2x-4)
2 x 2x - 2 x 4=4x-8
c) : x-8+3x
x+3x-8=4x-8

notice, we didn't use the negative value, valid though as it is, because in this case "a" can't be negative.
