$3 \: ( \: x + 2 \: )$

Plugging in the value $x = 5$ in the above expression, we have

$= 3\:( \: 5 + 2 \: )$

$= 3 \: ( \: 7 \: )$

$= 3 \times 7$

$= 21$

Answer:

$564$ tiles

Step-by-step explanation:

there are many ways to solve this soo...

1. convert to centimetres (there are 100 centimetres in 1 metre)

2. the square tiles area = $20*20=400cm$

2. find the large area (4.8m x 3.8m or 480cm x 380cm)

$480 *380=182400cm$

2. find the two smaller areas (1.2m x 1.8m or 120cm x 180cm)

$2(120*180)=4.3200cm$

3. add to find total area

$182400 +43200=225600cm$

4. find how many tiles are needed

$\frac{225600}{400}= 564$ tiles

What is the intercept of a line that has a slope of 3 and passes through point (-1,-7)?

IRISSAK [1]

Y = 3x + b
Now plug in points
-7 = 3(-1) + b
-7 = -3 + b
b = -4
The y intercept is -4
