The side oppoiste to the 8 ft side must also = 8 feet
which is a total of 16 feet

so the other  2 side measure (40-16) / 2 =  12 feet

Can someone help me figure out the answer?
olga_2 [115]

Answer:

y = -2x +15

Step-by-step explanation:

The point-slope form of the equation for a line through (h, k) with slope m is ...

... y - k = m(x - h)

For your point (h, k) = (5, 5) and slope m = -2, the equation in point-slope form is ...

... y - 5 = -2(x - 5)

Simplifying, we get

... y - 5 = -2x +10

Adding 5 puts the equation into slope-intercept form, as you want.

... y = -2x +15

GIVING 20 POINTS AND A BRAINLIEST!!!! (Really need help please!)
Murljashka [212]

Answer:

Step-by-step explanation:

General form of quadratic equation:

ax^2+bx+c=0

ax^2+bx=-c

To complete the square, we will divide the coefficient of x in the general quadratic equation as written above and divide by 2

I'm the question;

x^2-20x+13=0

x^2-20x=-13

The coefficient of x =-20

Divide the coefficient by 2 and square the result afterwards

-20/2= - 10

(-10)^2= 100

Add 100 to both sides of the equation

x^2-20x+100=-13+100

x^2-20x+100=87

x^2-10x-10x+100=87

x(x-10)-10(x-10)=87

(x-10)(x-10)=87

(x-10)^2=87

Answer is 10,87

What additional information could be used to prove ABC MQR using SAS?
Igoryamba

Answer:

To prove that ΔABC ≅ ΔMQR using SAS, we show that two sides with the intersection angle are congruent.

From the diagram, it is shown that CA is congruent to RM.

From the first option, given that m∠A = 64° and AB = MQ = 31 cm, then we have CA = RM, AB = MQ, and CAB = RMQ (i.e. m∠A = m∠M = 64°).

This shows that the first option is correct.

From the second option, given that CB = MQ = 29 cm, then we have CA = RM, CB = MQ, but ACB is not congruent to RMQ.

Thus the second option in not correct.

From the third option, m∠Q = 56° and CB ≅ RQ, then we have CA = RM, CB = RQ, ACB = 60°, but we do not know the value of MRQ.

Thus the third option is not correct.

From the fourth option, m∠R = 60° and AB ≅ MQ, then we have CA = RM, AB = MQ, RMQ = 64°, but we do not know the value of CAB.

Thus the fourth option is not correct.

From the fifth option, AB = QR = 31 cm, then we have CA = RM, AB = QR, but we do not know the value of CAB or MRQ.

Thus, the fifth option is not correct.

Therefore, the additional information that could be used to prove ΔABC ≅ ΔMQR using SAS is m∠A = 64° and AB = MQ = 31 cm
