Answer:
= 5 ( 12d + 23f )
Step-by-step explanation:
-2(5d-9f)+7f-10(-9f-7d
Open parenthesis
= -10d + 18f + 7f + 90f + 70d
Collect like terms
= -10d + 70d + 18f + 7f + 90f
= 60d + 115f
Factorise
= 5 ( 12d + 23f )
Therefore,
-2(5d-9f)+7f-10(-9f-7d) in its simplest form is 5 ( 12d + 23f )
1,000,000 is written as 10^6. Other wise it would be too low or too high.
Answer:
The measurement of AB is 16.25 units.
Step-by-step explanation:
In right triangle ABC, ∠C is a right angle, m∠A = 52° , AC = 10.01, and AB = c.
We need to find the measurement of AB.
∠C is a right angle, it means AB is hypotenuse.
In a right angle triangle,






Hence, the measurement of AB is 16.25 units.
Use the side lengths! C and D have lengths of 3 and heights of 4.
Also use how far away they are from the axis.
Both C and D are 2 away from each axis on the end point.
This also goes with A.
However, B does not seem to be congruent in the sense of (coordinates)
It is the same length and height.
Answer:
68 plants.
Step-by-step explanation:
Let x represent the number of plants that Reuben bought from the nursery.
We have been given that Reuben bought a whole bunch of plants at the nursery the other day. Right away, five died. So number of plant left would be
.
We are also told that then our dog dug up 2/9 of them. So number of plants left after dug-up would be
.
Further a rabbit came and ate ½ of what was left. So number of plants left would be
.
Since Reuben had only 7 plants left, so we will equate our expression with 7 and solve for x as:





Therefore, Reuben bought 68 plants at the nursery.
