Lt,[F(x)+2g(x)] x that’s the answer
Answer:
EF = 58
Step-by-step explanation:
Starting with the premise that
DF = DE + EF, then
9x - 39 = 47 + 3x + 10 ( subtract 3x from both sides )
6x - 39 = 57 ( add 39 to both sides )
6x = 96 ( divide both sides by 6 )
x = 16
Hence
EF = 3x + 10 = (3 × 16) + 10 = 48 + 10 = 58
Answer:
324
Step-by-step explanation:
((7*6) *4) + ((6*5) *4) + (6*6) =?
(42*4) + (30*4) + (6*6) =?
168 + 120 + 36 =?
324 =?
<em>Basically, you need to find the area of all sides and add it up.</em>
Answer:
a = 12
Step-by-step explanation:
as C^2 = A^2 + B^2
by Pythagoras theorem
so
A^2 = C^2 - B^2
= 13^2 - 5^2
= 169- 25
144
as 12^2 is equal to 144
hence side a is equal to 12
