Answer: If the hypotenuse is 7, the other 2 sides are 0r about = 4.95
Step-by-step explanation: in a 45-45-90 triangle, the legs are equal.
a² + b² = c² . 2(a²) = 49 a² = 49/2
So find the square root of 24.5
=4.949747468 .round to 4.95
Jaidee and Willie each improves their yards by planting rose bushes and geraniums. They bought their supplies from the same stor
1 answer:
The cost of one rose bush is $12 and cost of one geranium is $4.
Step-by-step explanation:
Let,
Cost of one rose = x
Cost of one geranium = y
According to given statement;
3x+12y=84 Eqn 1
8x+6y=120 Eqn 2
Multiplying Eqn 2 by 2
Subtracting Eqn 1 from Eqn 3
Dividing both sides by 13
Putting x=12 in Eqn 1
Dividing both sides by 12
The cost of one rose bush is $12 and cost of one geranium is $4.

Answer:
The expression that could be used is (-4)(3) + (-4)() ⇒ B
Step-by-step explanation:
Let us revise the distributive property:
<em>The product of a number and the sum of 2 other numbers equal to the sum of the products of the number with the other 2 numbers</em>
- a(b + c) = ab + ac
We will use this rule to solve the question
∵ The product of -4 and 3 = -4 × 3
→ We can right 3 as (3 +
)
∵ 3 = (3 +
)
∴ -4 × 3 = -4(3 +
)
→ By using the rule above
∵ -4(3 + ) = (-4)(3) + (-4)(
)
∴ -4 × 3 = (-4)(3) + (-4)(
)
∴ The expression that could be used is (-4)(3) + (-4)()
