Nope its B if you plug in
Answer:
A= 0.5 x (a+b) x h
124 = 0.5 x (12+19) x h
124 = 15.5 x h
÷15.5
h = 8cm
0.5x(12+19) x 8 does gives 124
Thus, height is 8cm.
Hope this helps!
4x - 26 = 2x - 4....subtract 2x from both sides
4x - 2x - 26 = -4...add 26 to both sides
4x - 2x = -4 + 26...combine terms
2x = 22...divide both sides by 2
x = 22/2 = 11
OR
4x - 26 = 2x - 4.....subtract 4x from both sides
-26 = 2x - 4x - 4....add 4 to both sides
-26 + 4 = 2x - 4x...combine terms
-22 = -2x....divide both sides by -2
-22/-2 = x
11 = x
Kites have two pairs of equal sides with one side shorter than the other. However, parallelograms have two pairs of equal sides, but they are parallel.
Answer:
42
Step-by-step explanation:
g(4) = 2x^2+5
= 2(4)^2+5
= 2(16)+5
= 32+5
= 37
f(g(4)) = 21+3sqrt(x+12)
= 21+3sqrt(37+12)
= 21+3sqrt(49)
= 21+3(7)
= 21+21
= 42
