Answer:
6 1/18
• There is no sentence below.
• There are no statements to check
Step-by-step explanation:
18x = 109
Divide both sides by 18
x = 109/18
x = 6 1/18
D. 62 because if we separate the shape into two then one will be 5*4 and the other will be 7*6. Adding them up will equal the whole shape.
Answer:
2 solutions:
x=5 and y=7
x=-1 and y=-5
Step-by-step explanation:
y=2x-3
y=x^2-2x-8
y=y so:
2x-3=x^2-2x-8
simplifying to:
x^2-4x-5=0
factoring to:
(x-5)(x+1)=0
x=5 or x=-1
if x=5 then y=2(5)-3=7
if x=-1 then y=2(-1)-3=-5
Perimeter of rectangle = all sides added
= 3+3+7+7 =20
volume of sphere = 4/3 x π x r(cubed)
= 4/3 x π X 4(cubed)
= 268.08257
area of triangle = base x height / 2
= 5 x 6 / 2
=30/2 =15
volume of pyramid = base height x base width x height / 3
= 300
side of triangle ---> use Pythagoras theorem so a(squared) + b (squared) = c(squared)
4(squared) + 3(squared) = c(squared)
16 + 9 = c(squared)
25 = c(squared)
c = 5
