Answer:
The length Of G is 3 cm
Length of F is 12cm
Ratio of lengths are 3/12
=1:4
Area of G=9cm²
Area of F=144cm²
Ratio of area=9cm²/144cm²
=1:16
Answer:
136
Step-by-step explanation:
GEMDAS
G - groupings
E - exponents
M - multiply
A - add
S - subtract
4.5 because 100/10 is 10 then do 10*5 to get 50.
Answer:
a = - 2 and b = - 3
Step-by-step explanation:
Distribute the parenthesis on the left side then compare like terms on both sides.
4(3x - 6) - 7(2x + b)
= 12x - 24 - 14x - 7b
= - 2x - 24 - 7b
Compare to right side ax - 3
For the 2 sides to be equal then
- 2x = ax ⇒ a = - 2
and
- 24 - 7b = - 3 ( add 24 to both sides )
- 7b = 21 ( divide both sides by - 7 )
b = - 3
