Answer:
Loonie is incorrect
Step-by-step explanation:
Both these numbers are divisible by 7. This means we can right the ratio keeping in mind every value added is like adding a 7. Now that we understand that 7 goes into these values we can divide them by 7. 35 divided by 7 is 5 and 42 divided by 7 is 6. The ratio would be 5:6 meaning Loonie is incorrect.
He is just tuning her out? and this is not really a math question make sure you put your questions under the right topic.
QS=5x-2
Because 3x+2x= 5x and -2 stays the same
Answer:
9m ×5m
Step-by-step explanation:
Area of a rectangle= length ×width
Let the width be W meters and the length be L meters.
2 equations can be written from the given information:
45= WL -----(1)
L= W +4 -----(2)
Substitute (2) into (1):
45= W(W +4)
<em>Expand:</em>
45= W² +4W
<em>-45 on both sides:</em>
W² +4W -45= 0
<em>Factorise:</em>
(W +9)(W -5)= 0
W+9=0 or W-5=0
W= -9 or W= 5
(reject)
Substitute W= 5 into (2):
L= 5 +4
L= 9
∴ The dimensions of the garden is 9m ×5m.
