Evaluate 10(a + b) -6c for a = 12,b = 5, and c = 9.

Gelneren [198K]

Answer:

10(a + b) -6c = 116

Step-by-step explanation:

Evaluate 10(a + b) -6c for a = 12,b = 5, and c = 9.

10(a + b) -6c = 10(12 + 5) - 6*9

10(a + b) -6c = 10*(17) - 54

10(a + b) -6c = 170 - 54

10(a + b) -6c = 116

Help me with the problem please!!

adell [148]

Step-by-step explanation:

Scale factor red to blue meaning 42 to 7

42÷7=6

Scale factor is 6

Perimeter of the blue quadrilateral = ?

If perimeter of red = 204

Then we use this following proportion

$204 \div 42 = x \div 7$

$\frac{204}{42} = \frac{x}{7}$

Then we cross multiply

42x=7×204

42x=1428

x=34

Area of the blue quadrilateral = ?

If area of the red quadrilateral = 2880

Then we use the following proportion

$2880 \div 42 = x \div 7$

$\frac{2880}{42} = \frac{x}{7}$

Then we cross multiply

42x=2880×7

42x=20160

x=480
