Answer:

Only area of PQR can be calculated.

Step-by-step explanation:

In PQR, we have both the base (24 cm) and the height (15cm) which is perpendicular to the base. Therefore using these two measurements, we can take

$\frac{1}{2} \times 24 \times 15$

This is equal to 180 cm².

Please help ! :0 -17 = 2y/3 + 3y/4

VashaNatasha [74]

Hi,

Equation;

$- 17 = \frac{2y}{3} + \frac{3y}{4}$

Solving:

$- 17 = \frac{2y}{3} + \frac{3y}{4} \: \: \: | \div 12 \\ - 204 = 8y + 9y \\ - 204 = 17y \\ 17y = - 204 \: \: \: | \div 17 \\ \\ y = - 12 \: \: \: \: \: \: \: \: (result)$

Hope this helps.
