Answer: no you can't you can only use 5 numbers when going by 4's
Step-by-step explanation: 4, 8, 12, 16, 20
Answer:
1.a=2
2. C x=2 and x=-3
Step-by-step explanation:
The standard form for the quadratic function is
ax^2 +bx+c
so we need to rewrite the function to be in this form
2x^2 -10 = 7x
Subtract 7x from each side
2x^2 -7x-10 = 7x-7x
2x^2 -7x-10 = 0
a =2, b= -7 c=-10
2. The quadratic formula is
-b ± sqrt(b^2 -4ac)
----------------------------
2a
2x^2 + 2x=12
Lest get the equation in proper form
2x^2 + 2x-12 = 12-12
2x^2 +2x-12 =0
a=2 b=2 c=-12
Lets substitute what we know
-2 ± sqrt(2^2 -4(2)(-12))
----------------------------
2(2)
-2 ± sqrt(4+96)
----------------------------
2(2)
-2 ± sqrt(100)
----------------------------

-2 ± 10

-2 + 10 -2-10

Answer: 2 2/3 cups of flour
Step-by-step explanation: If one batch represents 1/4 of the total number of cookies he needs, then it can be deduced that he needs four total batches. If it requires 2/3 cups of flour for each batch and he needs 4 batches, you would multiply 2/3 by 4 to get the answer.
2/3 × 4 = 2 2/3
44,000 *10
440,000
when multiplying by ten, add one more zero to the end of the number
Answer:
Step-by-step explanation:
- <em>Regular hexagons have a property that cutting off the triangles obtained by joining the midpoints of consecutive sides leaves a hexagon of 3/4 of the area.</em>
This means the area of each hexagon inside out starting from the one with unit area is 4/3 of the previous one.
- 99 ⇒ 1
- 98 ⇒ 1*4/3
- 97 ⇒ 1*(4/3)²
- ...
- 1 ⇒ (4/3)⁹⁹⁻¹
<u>The original hexagon has the area of:</u>
