According to Vieta's Formulas, if

are solutions of a given quadratic equation:
Then:
is the completely factored form of

.
If choose

, then:

So, according to Vieta's formula, we can get:

But

:
3 ft = 1 yd, Sandy has 156 ft of fabric = 52 yds
52 ÷ 7/8 = 52 × 8/7
52 × 8 = 416 ÷ 7 = 59 scarves.
<span>If m = the weight of boxes that marco lifted, and each box that drew lifted was 8 lbs less than marcos boxes, then you would multiply the total number of boxes that drew lifted by the weight of marcos total boxes - 8
or 14(m-8)</span>
Answer:
.
Step-by-step explanation:
Consider the double angle identity for tangents:
.
Also, for two complementary angles,
.
Subtract
from both sides of this equation:
.
Take the tangent of both sides of this equation:
.
Apply the double-angle identity to the left-hand side of this equation:
.
The two angles
and
are complementary. Therefore, for the right-hand side of this equation,
.
Equate the two sides of this equation:
.
