Answer:
13. B. 24 cm²
14. y = 5⅝ (none of the options is correct)
Step-by-step explanation:
13. The figure is a trapezoid
Area of the trapezoid = ½(a + b)h
Where,
a = 3 cm
b = 5 cm
h = 6 cm
Area = ½(3 + 5)6
= ½(8)6
= 4*6
= 24 cm²
14. Area of the triangle = ½*b*h
The area is given to be 45 cm²
base (b) = 16 cm
height (h) = y
Plug in the values and solve for y
45 = ½*16*y
45 = 8y
Divide both sides by 8
45/8 = 8y/8
45/8 = y
5⅝ = y
y = 5⅝ (none of the options is correct)
Answer:
yes
Step-by-step explanation:
1) a = 2, b= 3, c=2,
2) x^2 -2x-4 (a = 1, b=-2, c =-4)
3) x^2+x+3 (a,b = 1, c = 3)
4) 7x^2+8x-4 (a=7, b=8, c=-4)
Answer:
so the expression should be -2+7+2(2-(-3))
