Answer:
2A/ (b1-b2) =h
Step-by-step explanation:
A = 1/2 (b1-b2) *h
Multiply each side by 2
2A = 2 *1/2*(b1-b2) *h
2A = (b1-b2) *h
Divide by (b1-b2)
2A/ (b1-b2) = (b1-b2)/(b1-b2) *h
2A/ (b1-b2) =h
Answer:
AC = 12 cm
Step-by-step explanation:
AB=9 centimeters, you figure out what times what is 9. in this case, it is 3 for A and B. Then you go to BC=12 and 3 for B and 4 for C making it 12 So AC would equal 3x4.
Answer:
A right circular cone
Step-by-step explanation:
Answer:
x²+5x - 150 = 0
Step-by-step explanation:
Let the length be y and width be x
If the length of a swimming pool is 10 more than 2 times the width, then;
y = 2x+10 ...1
Since the Area is 300m²
A = xy
300 = xy .... 2
Substitute 1 into 2
300 = x(2x+10)
300 = 2x²+10x
Rearrange
2x²+10x - 300 = 0
Divide through by 2
x²+5x - 150 = 0
This gives the required quadratic expression
