Answer:

£90 more

Step-by-step explanation:

sum the parts of the ratio, 4 + 1 = 5 parts

Divide the amount by 5 to find the value of one part of the ratio

£150 ÷ 5 = £30 ← value of 1 part of the ratio, then

4 parts = 4 × £30 = £120 ← Ivan's share

£120 - £30 = £90

Ivanshal [37]

Answer:

Option C. 10.5(12 + x) square feet

Option E. (126 + 10.5x) square feet

Step-by-step explanation:

step 1

Find the area of the original living room

we know that

The area of the original living room is equal to

$A=LW$

we have

$L=12\ ft\\W=10\frac{1}{2}\ ft=10.5\ ft$

substitute

$A=(12)(10.5)=126\ ft^2$

step 2

Find the new area of the living room

The length of the room is being expanded by x feet

we have

$L=(12+x)\ ft\\W=10.5\ ft$

The new area is

$A=10.5(12+x)\ ft^2$

The expanded form of the expression is

Apply distributive property

$A=10.5(12)+10.5(x)\\A=(126+10.5x)\ ft^2$
