The perimeter of the rectangle below is 90 units. find the length of side vy . write your answer without variables.

Salsk061 [2.6K]

The picture in the attached figure

we know that
perimeter of a rectangle=2*[base+height]
base=3y+1
height=2y+3
perimeter=90 units
so
90=2*[(3y+1)+(2y+3)]-----> 90=2*[5y+4]----> 10y+8=90----> y=8.2 units

base=3y+1-----> base=3*8.2+1-----> 25.6 units
height=2y+3----> height= 2*8.2+3---> 19.4 units

the answer is
<span>the length of side vy is (2y+3)-----> 19.4 units</span>

Jim provides photos for two online sites: site A and site B. Site A pays $0.85 for every photo Jim provides. The amount in dolla

yarga [219]

We can use the same equation to figure out with only substituting the amount he was paid per photo.

Site A y = $0.85x = $0.85(5) = $4.25
Site B y = $0.40x = $0.40(5) = $2.00

We can see that Jim was paid $2.25 more at site A than Site B.

What are the zeros of the function f(x) = x2 + 8x + 4, expressed in simplest radical form? x = –4 ± 2StartRoot 3 EndRoot x = –4

SCORPION-xisa [38]

Answer:

Step-by-step explanation:

Discriminant Δ = √(8²-4×(1)×(4)) = √(48) = √(4×12) = √(4)×√(12) = 2√(12)

then x = (-8 ± 2√(12))÷2 = -4 ±√(12) = -4 ±√(3×4) = -4 ± 2√(3)

Jobisdone [24]

The answer is 21

First you po perenthies which would be 8-6=2 the equation now is 5+4×(2)2

Then you to exponents which would be 2×2=4 the equation now is 5+4×4

Now you multiply 4×4=16 the equation is now 5+16

Now you add 5 and 16 to get 21
