Step-by-step explanation:
11. shape 1 => A = ½×17×10=85m²
shape 2=> A = 17×9 =153 m²
total area = 238 m²
12. shape 1 => A = 7×3= 21 m²
shape 2=> A = 3×2 = 6 m²
total area = 27 m²
Answer:
g=3
Step-by-step explanation:
f(g) = g^2 +3g
Let f(g) = 18
18 = g^2 +3g
Subtract 18 from each side
18-18 =g^2 +3g-18
0 = g^2 +3g-18
Factor
0 = (g+6) (g-3)
Using the zero product property
g+6 =0 g-3 =0
g = -6 g =3
The only solution listed is g=3

Answer:
y = -5
x = -2
Step-by-step explanation:
x+7y=-37
2x-5y=21
Multiply first equation by -2
-2 × (x + 7y) = -37 ➡ -2x -14y = 74
now add the equation up
2x-5y -2x -14y = 21 + 74 (-2x will eliminate 2x)
-19y = 95 divide both sides by 19
y = -5 we can find the value for x by using this information
x + 7y = -37 replace y by -5
x + 7×(-5) = -37
x = -2
