How to solve the distributive property to express 27+60

Is H with an exponent of 2, be the same as h x h?

Elis [28]

Yes. This is because if you multiply 2 variables together you can make an exponent available. Also, you could do h to the first power plus h to the first power which would equal h ²

-2(bx - 5) = 16 What’s does b and x equal?

horrorfan [7]

To solve this problem you must apply the proccedure shown below:
You have the following equation given in the problem above:
-2(bx - 5) = 16
 When you solve for bx, you have:
-2(bx - 5) = 16
-2bx-10=16
-2bx=26
bx=26/-2
bx=-13

When you solve for b, you obtain:
-2(bx - 5) = 16
-2bx=26
b=-(26/2x)

When yoo solve for x:
2bx=26
x=-(26/2b)

Answer:

Area of trapezium = 4.4132 R²

Step-by-step explanation:

Given, MNPK is a trapezoid

MN = PK and ∠NMK = 65°

OT = R.

⇒ ∠PKM = 65° and also ∠MNP = ∠KPN = x (say).

Now, sum of interior angles in a quadrilateral of 4 sides = 360°.

⇒ x + x + 65° + 65° = 360°

⇒ x = 115°.

Here, NS is a tangent to the circle and ∠NSO = 90°

consider triangle NOS;

line joining O and N bisects the angle ∠MNP

⇒ ∠ONS = $\frac{115}{2}$ = 57.5°

Now, tan(57.5°) = $\frac{OS}{SN}$

⇒ 1.5697 = $\frac{R}{SN}$

⇒ SN = 0.637 R

⇒ NP = 2×SN = 2× 0.637 R = 1.274 R

Now, draw a line parallel to ST from N to line MK

let the intersection point be Q.

⇒ NQ = 2R

Consider triangle NQM,

tan(∠NMQ) = $\frac{NQ}{QM}$

⇒ tan65° = $\frac{NQ}{QM}$

⇒ QM = $\frac{2R}{2.1445}$

QM = 0.9326 R .

⇒ MT = MQ + QT

= 0.9326 R + 0.637 R (as QT = SN)

⇒ MT = 1.5696 R

⇒ MK = 2×MT = 2×1.5696 R = 3.1392 R

Now, area of trapezium is (sum of parallel sides/ 2)×(distance between them).

⇒ A = ( $\frac{NP + MK}{2}$ ) × (ST)

= ( $\frac{1.274 R + 3.1392 R}{2}$ ) × 2 R

= 4.4132 R²

⇒ Area of trapezium = 4.4132 R²

A plant has two alleles for color. The red allele is recessive and is represented by q. The purple allele is dominant and is rep

LenaWriter [7]

We are given with two alleles for color: one is the red allele and the other is the purple allele. The equation that represents the two alleles is expressed p^2+2pq+q^2=1. We are given with 0.30 probability for the red allele. we substitute this to the equation to determine the purple allele probability, q. The answer is D. 0.7
