What is a number that when you subtract it by 8 and then multiply by 7 will equal to 28?
Answer:
n = 12
Step-by-step explanation:
(n-8)x 7 = 28
n-8 = 4
n = 12
Answer:
12
Step-by-step explanation:
(x - 8) * 7 = 28
Divide both sides by 7
x - 8 = 4
Add 8 to both sides
x = 12

find sum of the roots
full questions is up there in the photo attached
helppp plz :(
Answer:
C. -4/3
Step-by-step explanation:
Start by finding the roots of the equation by factorising.
3x³+4x²-4x=0
x(3x²+4x-4)=0
x(3x-2)(x+2)=0 [because (ax+b)(cx+d)=(ac)x²+(ad+bc)x+(bd)]
If multiplying these three terms works out to be zero, we know that one of the terms must be zero, as anything multiplied by zero is zero.
So
x=0, or 3x-2=0, or x+2=0
Which means our roots are
x=0, x=2/3, x=-2
Now find the sum of these roots: 0+(2/3)-2=(2/3)-(6/3)=-4/3

Answer:
THE CORRECT ANSWER IS B- 73 FEETThe given condition in question will form a right angle triangle
and the length of sides of triangle are given 55ft, 48ft and missing one.
Now using pythagoras theorem,55²+48²= x²
x² = 3025 + 2304
x² = 5329
Taking square root of 5329 will give 73 ft!

Aubrey tried to prove that sin(θ)=cos(180°−θ) using the following diagram. Her proof is not correct.
Answer:
Angles ∠B and ∠C are complementary, not supplementary.
Step-by-step explanation:
I took the test. (khan academy)
Her proof is not correct because angles ∠B and ∠C are complementary, not supplementary.
What angles are not supplementary?If you add two acute angles in which each angle is large as possible, its sum will be less than 180°. By the definition of supplementary angles, it is impossible to get the supplementary angle when we add two acute angles.
How do you know if angles are complementary neither or supplementary?Supplementary angles are two angles whose sum is 180 degrees while complementary angles are two angles whose sum is 90 degrees. Supplementary and complementary angles do not have to be adjacent, but they can be.

(b) If AD was parallel to BC, <A would be equal to (180-<B)=90 (corresponding angles). Since <A≠90, we can see that AD and BC aren't parallel.
Step-by-step explanation:
(a)
Angles in a quadrilateral add to 360:
<A+<B+<C+<D=360
2x+90+x+3x=360
6x=270
x=45°
(b)
If AD was parallel to BC, <A would be equal to (180-<B)=90 (corresponding angles). Since <A≠90, we can see that AD and BC aren't parallel.
Answer: Step-by-step explanation:
3x+2x+x=360-90
6x=270
x=45
∠DAB=2x=90° and ∠ABC=90° ⇒ AD║BC

-5(x-5)=2(-4x+5) find x step by step please
Answer: -5
Step-by-step explanation:
-5(x-5)=2(-4x+5)
-5x + 25 = -8x +10
3x +25 = 10 (add 8 from both sides)
3x = -15 (subtract 25 from both sides)
x = -5 (divide 3 from both sides)

ΔDEF and ΔJKL are congruent to each other.
TriangleTriangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.
Right angle triangleIt is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.
Given
DF = JL = a, FE = LK = b,
And ΔDEF is a right triangle.
To findΔDEF and ΔJKL are congruent to each other.
How to find the ΔDEF and ΔJKL are congruent to each other?Since the Pythagoras theorem is applicable in ΔDEF.
a² + b² = c²
This equation also satisfies the ΔJKL Hence angle K is the right-angle.
Since, ∠F = ∠L = 90°,
DF = JL = a,
FE = LK = b
Therefore, ΔDEF ≅ ΔJKL
Thus, ΔDEF and ΔJKL are congruent to each other.
