Solve for x. And graph 7(3x+4)+2<156

blsea [12.9K]

$7(3 \times x + 4) + 2 < 156 \\ 21 \times x + 28 + 2 < 156 \\ 21 \times x + 30 < 156 \\ 21 \times x < 156 - 30 \\ 21 \times x < 126 \\ x < \frac{126}{21} \\ x < 6$

kaheart [24]

Answer:

616

Step-by-step explanation:

The equation to find the area of a trapezoid is: A = ½ (b $^1$ +b²) h.

b1=43

b2=45

h=14

Plug the variables in and solve.

$A=\frac{1}{2} (43+45)14$

$A=\frac{1}{2} (88)14$

$A=\frac{1}{2} (1232)$

$A=616$
